Rio Tinto Plans to Expand Scandium Sales Amid Growing Demand for High-Strength Aluminum Alloys

Rio Tinto, a major British resource company, is preparing to increase its sales of scandium, a byproduct of titanium dioxide production, in response to rising demand. The company sees substantial growth potential for scandium oxide, particularly for use in high-strength aluminum alloys. Currently producing 3 tons of scandium annually in Canada, Rio Tinto is considering investing in increased production to meet the expanding market. A scandium mine development project is also underway in Australia.

Scandium oxide is gaining interest for applications such as solid oxide fuel cells, LEDs, and lasers. However, the largest anticipated demand comes from its use in aluminum alloys. Adding small amounts of scandium to aluminum alloys can significantly increase their strength, making them suitable for industries like aerospace and electric vehicles where both lightness and strength are essential.

Rio Tinto is also exploring broader uses for scandium metal, particularly in high-performance electronic components such as microchips. To meet this rising demand, the company is considering quadrupling its production capacity in Canada to 12 tons annually. Additionally, the Australian project, currently in the feasibility study phase, could produce 40 tons of scandium per year if commercialized, significantly boosting global supply.
