The Coming Copper Shortage: Aluminium Or Carbon Nanotubes To The Rescue?
(but first, a detour)
Kryron — The Revolutionary Material - Kryronized aluminum is a carbon nanotube metal matrix composite (CNT-MMC). Kryronized materials are superior to other CNT-MMC variants because Bourque Industries has solved two key problems commonly associated with CNT-MMC's, homogenous distribution of carbon nanotubes within the metallic substrate and cost effective performance on an industrial scale. The infusion of carbon nanotubes into our proprietary metal alloy allows us to create materials with exceptional ballistic capability and low weight.
(end of detour)
Aluminium has one major benefit over copper, and that is that it is twice as electrically conductive by mass, owing to copper’s density at room temperature.
The Yazaki company of Japan has filed numerous patents

on Al-CNT composite materials that are intended to be used in upcoming wire products.
Tirupati Graphite Plc

meanwhile has made claims

about an Al-graphene composite that claims to have copper-like electrical conductivity, better thermal conductivity than copper and better micro-hardness than copper.
The addition of CNTs has also found use in other applications, such as the mechanical reinforcement of aluminium parts, with Nyanor et al. (2020), detailing an aluminium matrix reinforced with CNTs as well as micron-sized titanium-carbide (TiC) particles. This creates a material that has 2.3 times the hardness of pure aluminium, with significantly improved wear resistance.
Perhaps more exciting is the prospect of graphene and CNT-based wiring, which offers more than just a trade-off compared to copper. Instead these may result in an alternative to copper that is actually better in all respects, with better conductivity, higher tensile strength, higher resistance to corrosion and higher conductivity for both a given cross-section and weight.
