Scandium Price
With only 10 to 15 tonnes of scandium produced globally each year due to the scarcity of supply and limited production, scandium is one of the most expensive metals in the world. Prices for 99.99% pure scandium oxide have fluctuated between US $4,000 and US $20,000 per kilogram over the past decade, according to Strategic-metal.com. Due to this current limited market, there is a wide range of prices offered for the metal at any given time. A recent offer (September 2017) for 99.9% scandium concentrate was at US $15,000 /kg.
Currently the prices for scandium oxide can range from $2,000–$5,000/kg. It’s thought that as the scandium supply increases the pure scandium oxide will come down in price to perhaps $1,500 to $2,500 a kg.
Depending on the percentage of the scandium alloying element added to the mix, the prices of the alloys are expected to cost between 30% more than non-scandium alloy (at scandium levels of between 0.06% up to 0.12%.)
