Scandium has important uses in environmentally preferred Solid Oxide Fuel Cells, as well as in ultra-high-performance aluminum alloys. Scandium greatly strengthens aluminum alloys and allows them to be reliably welded, which presents revolutionary potential for the commercial airline industry. For example, between $1.0-$1.5 million of scandium oxide in a single airliner offers $10-15 million in net present value fuel savings.

Major Uses of Scandium
Major uses of Scandium today are in Solid Oxide Fuel Cells, high-performance aluminum alloys, high-energy lasers, stadium lighting, and other uses.
Consumption Constrained by Supply
Current global consumption of Scandium is only 10-15 tonnes per year, and is constrained by limited, unreliable and inefficient supply sources.
Strong Demand Growth Forecast
With a reliable supply of Scandium, demand for this high-performance metal is forecast to grow strongly. Estimated demand in the aerospace sector alone is about 300 tonnes per year.
Disruptive Potential of Scandium
Scandium is poised to deliver truly revolutionary benefits to the commercial aviation and other industries. For example:
- An analysis by OnG Commodities LLC shows that Scandium-contained aluminum alloys can save airline operators approximately $9 million in net present value for a single B737-sized jetliner, assuming Scandium oxide pricing at $3,500/kg. This represents an 11:1 cost-savings ratio for the airlines.
- This analysis assumes a B737 flying 3,250 hours per year, using American Airlines’ cost of capital, U.S. Energy Information Agency projections for future fuel price inflation, a per-kilogram price for scandium oxide of $3,500/kg, and an average 0.7% by weight scandium doping level.
Addition, for commercial aircraft manufacturers, AlSc alloys allow aluminum components to be welded instead of joined via hundreds of thousands of rivets per plane. For manufacturers, this could amount to:
- Tens of millions of dollars/year in lower materials costs and direct manufacturing costs.
- Higher manufacturing throughput: a 1% increase in annual production of a narrow body jet is worth ~$500 million in added revenue to an OEM.
Scandium alloys also present potentially revolutionary weight and cost savings to other transportation systems, such as cars, trucks, buses, trains and other platforms.

As the U.S. looks to repair crumbling infrastructure systems, I expect to see more high-performance steels (HPS) used in structures like bridges because of the many powerful benefits they deliver. HPS steels containing a small amount of ferroniobium – which NioCorp plans to produce in southeast Nebraska at our Elk Creek Superalloy Materials Project once we are funded and in operation – are among the strongest and most durable steels on the market today.
If a $2 trillion U.S. infrastructure package is enacted, it could create a major, long-term demand boom for the critical minerals needed by infrastructure and advanced transportation systems, according to NioCorp’s CEO Mark Smith.
One global macro trend is highly likely to accelerate in the aftermath of COVID-19: increased investment in domestic materials supply chains as a means of reducing the reliance of Western nations on supply chains in developing nations. Asia’s dominance in many strategic supply chains has become painfully obvious since the COVID-19 pandemic erupted.
