R&D and upgrade-magnesium aluminum alloy, liquid metal, and medical magnesium materials work together
Securities Research Report | First Coverage Report May 26, 2021
Core Aspects:
Industry leader in the fields of magnesium aluminum alloy, liquid metal, and medical magnesium materials. The company has a complete magnesium-aluminum alloy industry chain, based on its main business, has a position in the fields of liquid metal and medical magnesium materials, and builds a new growth point for the company. Its subsidiaries Yihao Metal and Meian Medical are the company’s "main battlefields" for liquid metal and medical magnesium materials.
Liquid metal will bring about the third material industrial revolution, and the company masters formulas and core patents for die-casting. Liquid metal (also known as amorphous alloy) has excellent physical and chemical properties such as high strength, high hardness, wear resistance, and corrosion resistance. With the advancement of die-casting technology, it currently has the potential for mass production and has the ability to form complex structures at one time. The cost efficiency advantage is significant. The company holds the core patents of liquid metal formulas and process equipment. LQMT (United States), a subsidiary of Hong Kong Liquid Metal Co., Ltd., which is 100% owned by the chairman, has played a synergistic role with the company to consolidate the company's leading position in Liquid Metal. The zirconium-based liquid metal material has been officially selected as an important material for the hinge of Huawei's second-generation folding screen mobile phone Mate Xs. With the promotion of zirconium-based metal applications, the company's product market has a broad space.
Biodegradable medical magnesium alloys benefit orthopedic patients, and the clinical and industrialization process is advancing steadily. Magnesium is a major element of the human body, which can be degraded and absorbed after implanted in the human body, avoiding the pain and risk of secondary surgery, and its mechanical properties are close to that of human bone tissue; and magnesium ions can promote bone formation and accelerate the rate of bone formation, and the cost is lower than traditional titanium alloys Material, so it has obvious advantages in orthopedics applications. The company's domestic clinical trials of high-purity magnesium bone nails are steadily advancing, and they have successfully obtained the EU CE certification and the right to enter the EU market. In the future, they will open up a tens of billions of blue ocean market.

New energy vehicles accelerate the process of lightweight vehicles, and join hands with Yunhai Metal to create an aluminum-magnesium alloy “Yangtze River Delta + Pearl River Delta” layout. Magnesium aluminum alloy is a lightweight structural material for automobiles. At present, new energy vehicles generally have problems such as overweight and short cruising range. Increasing the proportion of lightweight materials in the entire vehicle is an effective way to increase the cruising range of new energy vehicles. The development of the new energy vehicle industry, The introduction of national policies such as environmental protection will accelerate the process of automobile lightweighting. In 2020, the second phase of the company’s “Chaohu Yi’an Yunhai Light Alloy Precision Die Casting Production Base Project” will be completed (the first phase will be put into production in 2017), achieving stable supply of raw materials and the location advantage of the “Pearl River Delta + Yangtze River Delta” dual center layout. Enter the supply chain of well-known domestic and foreign customers such as BYD and Tesla.
Investment advice: The company’s liquid alloy masters the core formula and equipment patents, and the zirconium-based liquid metal cuts into the core mobile phone manufacturer’s supply chain. It is expected to open up the company’s business profit growth point; on the other hand, the company’s new energy vehicle light
We have accumulated rich experience and R&D advantages in quantitative materials, and our products have successfully entered the supply chain of well-known customers at home and abroad, and are expected to enjoy incremental market gains in the future. The company has accumulated and first-in-class advantages in the industrialization of medical magnesium alloys, and the industrial value of magnesium alloys is expected to be realized after the clinical promotion of medical magnesium alloys. We expect the company’s net profit attributable to the parent company to be 0.41, 0.55, and 74 million yuan in 2021-2023, corresponding to 107.4, 80.0, and 59.1 times of PE. Considering that the company’s current business is still in the early promotion stage, there is still uncertainty in subsequent performance growth. The first coverage is given a "hold" rating.
Risk warning: orders for related new materials are lower than expected; the industrialization of liquid metal is not as expected; the performance of the main business of magnesium and aluminum alloy is not as good as expected; the clinical application of medical magnesium alloy is slower than expected.

Amorphous alloys: Amorphous alloys are also called liquid metals, solid metals or alloys whose atoms are arranged in a long-range disorder and short-range ordered structure. The microstructure is very similar to that of glass, so it is called liquid metal. Amorphous alloy has high strength, high hardness, high elastic limit, good soft magnetic or hard magnetic properties, friction and wear resistance and corrosion resistance and other excellent physical and chemical properties, and its cooling and solidification shrinkage is small, and it has a good near-net shape Casting forming ability (high precision in one-time forming, which can save machining cost).
? Performance advantage: a new type of metal material with the characteristics of glass, metal, solid and liquid. Because there are no defects such as dislocation, stacking fault, grain boundary, etc., amorphous alloys show special mechanical properties, and their bending strength, tensile strength, elastic deformation, etc. are better than common materials (strength is more than 5 times that of conventional aluminum-magnesium alloys) , 7 series aluminum is 5 times, stainless steel is 3 times, titanium alloy is 2 times).
? Potential for mass production: Liquid metal can be produced through molds. A set of molds supports 30,000 to 40,000 products. At present, Yi'an Technology's products have high repeatability and accuracy can reach ±0.03mm. Compared with powder metallurgy, liquid metal The transverse and longitudinal shrinkage rate reaches 2.5-3.5 per thousand, and the powder metallurgy shrinkage rate is 22%-24%, which is more suitable for batch preparation of precision metal structures requiring high precision.
? Cost advantage: Liquid metal can form products with complex structures at one time through vacuum die-casting. Because of its good formability, it saves a lot of CNC (Numerical Control Processing) procedures and has a high cost performance. And due to the good material properties, compared with traditional materials, the same structural strength requires less liquid metal material consumption, and the cost advantage of scaled production is highlighted.
Figure 13: The mechanical properties of liquid metal are better than common materials
The four major sectors are working together to continue to expand the downstream application areas: the company’s largest liquid metal sector is liquid metal hinges for folding screen mobile phones.

2.3 The production of bulk amorphous alloys is relatively difficult, and large-scale bulk amorphous alloys still need technological breakthroughs
After nearly a hundred years of development, amorphous alloys have continuously enriched their alloy components: In 1934, German scientist Kramer first used meteorological deposition to prepare amorphous alloy films. In 1950, Brenner prepared a Ni-P amorphous alloy coating by electrodeposition to improve wear resistance and corrosion resistance, and was widely used in continuous casting and rolling molds in the iron and steel smelting industry. In 1987, the metal copper mold casting method used by the Institute of Metal Research of Tohoku University in Japan discovered La-Al-Ni-Cu (lanthanum series), Mg-Y-Ni-Cu (magnesium series) and Zr-Al-Ni-Cu (zirconium series), etc. A bulk amorphous alloy system with strong amorphous forming ability. Later, Peker and Mukherjee of the California Institute of Technology in the United States discovered the Zr-Ti-Cu-Ni-Be alloy system with superb amorphous forming ability through the method of doping with metal Be.
Bulk amorphous alloys are difficult to produce, and vacuum die-casting is suitable for thin-walled complex parts: amorphous alloys have metastable structure characteristics, and it is difficult to use conventional forging or welding processes for parts processing. The current feasible technical means is the use of blocks. The fluidity of bulk amorphous alloy is cast. Crystalline alloys are solidified under equilibrium conditions, and since rapid cooling is not required, the mold can be easily filled. Because of the metastable characteristics of amorphous alloys, the alloy liquid must freeze its liquid structure into a solid state at a very fast cooling rate, and there is no release of latent heat of crystallization during the process, which brings about the filling ability and fluidity of amorphous alloys. Problems, such as insufficient pouring and air pockets. In order to solve these problems, the current common technological methods are: superplastic forming, vacuum die casting (injection) forming, vacuum suction casting forming, water quenching method, copper mold adsorption method, directional solidification method and other processes.

Current technology is difficult to achieve large-scale mass production of bulk amorphous alloys: limited by the manufacturing process of amorphous alloys, if the size is large, it is difficult to achieve amorphization inside, so there is a size limit (maximum critical size) in the manufacture of amorphous alloys . The maximum critical dimension of most types of amorphous alloys is within 10mm. The Pd-based alloy invented in 1997 reached 72mm. In 2019, Shen Baolong of Southeast University and others obtained non-gold alloy ingots with a maximum diameter of 16.52mm through arc melting and negative pressure direct cooling. , But there is still a big gap compared with other alloys, which limits the application of amorphous materials to a certain extent. In the future, with technological progress, bulk alloys are expected to break through the size limit of structural parts and realize the large-scale production of large super-strong structural parts.
2.4 The company's amorphous alloy is in a leading position in China
The earlier bulk amorphous alloy forming equipment in the world is the amorphous alloy injection equipment developed by Liquidmetal Technologies in the United States and ENGEI in Europe in 2015, but the forming equipment developed and manufactured by it is the company’s secret and is not external. Sales, so its details are not clear to the outside world. Huawei, BYD, Foxconn and Yi'an were among the earliest domestic companies that started industrializing bulk amorphous alloys. Since 2008, BYD has opened

Biodegradable medical magnesium alloys have been successfully used in orthopedic implants: Magnesium and its alloys as medical biomaterials can be traced back to 1878. Edward used pure magnesium wire as a ligature to ligate blood vessels to stop bleeding; until 1900, Payr proposed to use it. Pure magnesium is used as bone material. Lambotte used pure magnesium plates to treat lower limb fractures in 1907. Early clinical application studies have found that magnesium is biologically safe and can promote bone healing; however, because magnesium is degraded too quickly in the body, fractures have not healed, and internal fixation fails. After a long period of time, magnesium and magnesium alloys Clinical research has basically stopped.
The main problem is the excessively fast degradation rate and the generation of air pockets: Magnesium and magnesium alloys may cause insufficient fixation in the early stage of the patient's recovery period due to the excessively fast degradation rate and severe degradation morphology, and thus cannot bear the fixation of the bone mass of the load-bearing part; At the same time, due to the active chemical nature of magnesium in the body, the potential is low (-2.37V vs SHE (standard hydrogen electrode)). In a liquid environment rich in Cl -, galvanic cells are easily formed between the matrix and the second phase, resulting in galvanic coupling. Corrosion and gas generation at the same time, the chemical reaction formula is as follows:
Mg+2H2O+2Cl- ?MgCl2 +H2 +2OH- With the breakthrough of smelting technology and the improvement of casting process, on the one hand, the purity of magnesium has been greatly improved, on the other hand, zinc, calcium, manganese, aluminum, rare earth and other elements are added The formation of magnesium alloys significantly improves the corrosion resistance and mechanical properties of magnesium and its alloys, so that magnesium and its alloys as biodegradable medical materials have once again attracted attention and become one of the research focuses and hotspots in the field of medical biomaterials at home and abroad.
3.1.1 Compared with traditional titanium alloy, stainless steel and other alloy materials, magnesium alloy has significant advantages
? Corrosion and degradation in the body and full absorption, avoiding secondary operations. Magnesium and magnesium alloy materials have good biocompatibility with the human body, avoiding the pain and wounds of secondary operations. This has a good application prospect for facial plastic surgery. .
? Magnesium is a macro-element in the human body and has good biocompatibility. After being implanted in the human body, magnesium bone nails can undergo dynamic degradation behavior, and its degradation products will not cause allergic reactions in the human body. Magnesium ions are the fourth largest metal in the human body. Elements, adults need to take in 300-400 mg of magnesium every day, and excessive Mg2+ can be excreted through urine. At the same time, magnesium alloy has good cell compatibility, and cells can effectively attach, diffuse and proliferate on the magnesium alloy.
? Good comprehensive mechanical properties, close to human bone tissues. Compared with traditional titanium alloys, cobalt-chromium alloys, stainless steel and other traditional alloy materials, magnesium and magnesium alloy materials have a density and elastic modulus that match human bones. It can largely avoid the stress shielding effect after implantation, that is, when two or more materials with different rigidity bear external force together, the material with higher rigidity will bear higher load, while the material with lower rigidity will bear higher load. The material only needs to bear a low load, causing stress to concentrate on the interface between the bone and the implanted bone nail, thereby reducing the stability of the bone nail and inhibiting the growth of new bone.
? Mg2+ has biological activity and accelerates the rate of bone formation
In bone repair, Mg 2+ stimulates the spinal ganglia to release calcitonin gene-related peptides, induces the production of related proteins, and promotes bone formation. Therefore, magnesium alloys are often used as medical devices for internal fixation of fractures.
? As a common metal, magnesium costs much lower than titanium alloys.

3.1.2 High purity magnesium VS magnesium alloy: single element, stable degradation rate
? Single element, no need to consider the effects of multi-element toxicity. Compared with European rare earth magnesium bone nail products, the degradable magnesium bone internal fixation screw developed by Mei'an is made of 99.999% high-purity magnesium. Due to the single element, it avoids the influence of other elements. The impact is more stable and harmless.
? Stable degradation rate and controllable cavitation generation. Previously, rare-earth magnesium alloy bone nails have reported bone cysts, cavitation caused by excessive degradation, and joint fusion failures caused by cavitation. Compared with magnesium alloys, high purity magnesium (>99.9%) is an effective method to reduce the degradation rate. In 2013, the chief scientist of Eian Technology, Professor Zhao Dewei of Zhongshan Hospital of Dalian University, performed the world's first pure magnesium bone nail for femoral necrosis with vascularized bone flap transplantation. So far, more than 100 cases have been completed, and the treatment effect is very good. The results also show that the high-purity magnesium bone nail has an acceptable degradation rate, which not only meets the fixation requirements at the initial stage of the operation, but also because there is no obvious air pocket formation, it will not affect the fusion of the graft and the tissue. The degradation product magnesium ions will instead promote the surrounding bone The formation of the organization.
Figure 25: The first case of pure magnesium bone nail applied to femoral necrosis with vascularized bone flap transplantation Figure 26: Common joint fractures
3.2 The successful clinical trials of medical magnesium bone nails will open up the tens of billions of medical equipment market
The company's high-purity magnesium bone nails are the first to enter the clinical trial phase: In 2008, Yian Technology, with the joint research and development and help of some university professors, began to develop a magnesium preparation method with a purity of 99.999%. A wholly-owned subsidiary of Yian Technology: Dongguan Mei'an Medical Devices Co., Ltd., which has focused on the development of the medical magnesium industry for many years. At present, the clinical trials of magnesium bone nails by Mei'an Company are mainly used for avascular necrosis of the femoral head and for vascularized bone flaps. The internal fixation of the bone flap during transplantation will continue to expand the indications in the follow-up. In July 2019, the degradable magnesium internal fixation screw developed by Mei'an became the first domestically approved biodegradable biodegradable screw.

4. New energy vehicles support the magnesium-aluminum light alloy business sector
The profitability of the magnesium-aluminum alloy business is still under pressure and remains the company's main source of revenue: In 2020, the company's magnesium-aluminum alloy business revenue was 578 million yuan, a year-on-year decrease of 18%; the gross profit margin in 2020 was only 8.0%, which was 18.5% in 2019 dramatically drop. The company's magnesium products business revenue decreased by 20.5% year-on-year, and costs decreased by 11.3% year-on-year; aluminum product revenues decreased by 13.9% year-on-year, and costs decreased by 1.5% year-on-year. It can be seen that as market competition intensifies, the company's magnesium-aluminum alloy products will be under pressure in the future. The company needs to further reduce costs and increase efficiency, and increase the proportion of high-margin products.
4.1 Lightweight vehicles open up the magnesium-aluminum alloy market space, and new energy vehicles are expected to accelerate the lightweight process
Automobile lightweight opens up market space for magnesium-aluminum light alloys. There is still a gap between the amount of aluminum-magnesium used in bicycles in my fcountry and foreign car companies: magnesium alloys, together with aluminum alloys, have become ideal materials for lightweight vehicles due to their light weight, high specific strength and high specific rigidity. Moreover, as the lightest metal structural material, magnesium alloy is more effective than aluminum alloy in reducing weight, and the room for increasing the amount of magnesium used in bicycles is also broader than aluminum. Under the condition of equal bending rigidity, the use of aluminum alloy instead of steel can reduce the dead weight by 61%, and the magnesium alloy can achieve 74%. According to the "Overview of the Situationalization of New Energy Vehicles", for every 10% reduction in the quality of new energy vehicles, the corresponding cruising range can increase by 5%-10%, saving 15%-20% of battery costs and 20% of daily loss costs, and new energy vehicles reduce weight The demands are more urgent than traditional cars.

New energy vehicles drive the demand for new magnesium-aluminum alloy materials: How to improve the energy density ratio of power batteries, and realize the lightweight and structural safety of battery boxes, has become the first issue for new energy vehicle manufacturers to consider. The comprehensive cost performance of new materials such as magnesium-aluminum alloy is higher than that of steel, plastics and composite materials, and they are ideal materials for lightweighting new energy vehicles. Tesla Model S uses an all-aluminum body, and the weight is reduced to 2.1 tons. In order to increase the cruising range of new energy vehicles, the proportion of aluminum and magnesium alloy components may be further increased in the future.
According to data from the China Association of Automobile Manufacturers, in 2020, the production and sales of new energy vehicles will be 1.366 million and 1.367 million respectively, a year-on-year increase of 7.5% and 10.9% respectively. In October 2020, the State Council formally issued the "New Energy Vehicle Industry Development Plan (2021-2035)", which made requirements in terms of technology development and innovation, infrastructure construction, and the use of new energy vehicles in the public service sector, and clarified that by 2025, China's new energy vehicle sales accounted for about 25%.

The establishment of a joint venture company with Yunhai Metal in Chaohu and the construction of production capacity this time have a very positive significance for realizing the strategic layout of the Yangtze River Delta, reducing material costs, and expanding and strengthening the 3C and automotive magnesium alloy business.
First, ensure the supply of raw materials and significantly reduce costs. The company is close to the Chaohu Yunhai magnesium alloy production line (with an annual output of 50,000 tons of magnesium alloys). The joint venture with Yunhai Metal can reduce the cost of raw material transportation. It can be directly supplied through molten magnesium water, eliminating the cost of magnesium alloy ingot smelting and the cost of raw materials. Oxidation consumption, finally, can also be recycled through waste magnesium to form a closed loop, further reducing costs. According to the company's preliminary calculation, the cost of magnesium alloy raw materials for the project will be reduced by about 15%-20% compared with the current one, which greatly enhances the cost advantage of the company's products. At the same time, using Yunhai Metal's existing construction land in Chaohu, the project was implemented very quickly.
Second, occupy the golden area of ??the light alloy die-casting market in the Yangtze River Delta and realize the strategic layout of "Pearl River Delta + Yangtze River Delta" dual centers. Since the establishment of the company, the place of operation has been in the Pearl River Delta region. The Yangtze River Delta region is one of the largest automobile production bases in my country. There are well-known automobile manufacturers such as SAIC, Shanghai Volkswagen, Shanghai GM, etc., and the country's most comprehensive and largest auto parts industry cluster; in Anhui Province , There are automobile manufacturers such as Chery Automobile, Jianghuai Automobile and Hefei Changan.

5. Profit forecast and investment advice
P.24
Please read the statement on the last page of this report carefully

5.1 Earnings forecast assumptions
Operating income
The core of the company's current revenue comes from the sales of core aluminum and magnesium products. As the company's current core business, it is expected to open up a broader market space for the company after its applications in the fields of medicine and automobiles are gradually promoted. At the same time, taking into account the company's own competitive advantages in segmented areas, we reasonably expect the company's operating income from 2021 to 2023 to be 11.88, 15.24, and 1.905 billion yuan, corresponding to growth rates of 25.6%, 28.3%, and 25.0%, respectively.
Gross margin
The gross profit margin of the company's magnesium-aluminum alloy products is affected by the fluctuation of the corresponding metal prices, and the gross profit margin is subject to certain volatility. We reasonably assume that the subsequent gross profit margin of the company's main operations will stabilize, and the high gross profit portion from liquid metal sales is expected to gradually increase the company's overall gross profit margin. We expect the company's gross profit margin to achieve 21.48%, 21.89%, and 22.02% in 2021-2023, respectively.
Period expense ratio Sales expense ratio: The company's sales expense ratio is expected to drop significantly in the future. The core reason is that the company's current main business has successfully docked with the core customer groups in the industry, and it is expected to form a long-term binding relationship with customers in the future, and sales expenses will reduce the erosion of profits. Management expense ratio: The company's daily expenses are mainly concentrated in management expenses. As the company's current business segments are still in a period of heavy performance, the core management team still needs to be filled as the business gradually expands. We expect the company's management expenses and revenue scale to grow at the same rate. R&D expense ratio: The company's R&D expense is mainly connected to the current core business segments. Considering that the company has formed a leading position in the subdivision field and possesses R&D advantages, and its products have been recognized by core customers at home and abroad, the subsequent R&D expense rate is expected to remain stable.
