Infinium has been contracted by the US Department of Defense's (DoD) Defense Logistics Agency to supply dysprosium-iron metal.
Dysprosium plays a key role in the production of magnets that can be used in several major defence systems, such as advanced fighter aircraft, naval vessels, and ground equipment.
The magnets produced will be able to perform at high temperatures.
Under the contract, the company will provide dysprosium-iron metal for the National Defense Stockpile as mandated by Congress in the Fiscal Year 2014 National Defense Authorization Act.
The National Defense Stockpile is a branch of the Defense Logistics Agency that stores, secures, and sells raw materials.
It sells aluminium oxide, beryllium, chromium, cobalt, diamonds, ferrochromium, ferromanganese, iodine, iridium, mica, niobium, platinum group metals, talc, tantalum, thorium, tin, tungsten and zinc.
Infinium CEO Steve Derezinski said: "We are thrilled to be entrusted by the Department of Defense to supply the National Defense Stockpile with their only domestically manufactured rare earth material.
"Our clean metal processing capability represents the only commercial production of rare earth material in the US today, and we look forward to growing our partnership with the Defense Department.”
The clean technology process employed by the company will help to eliminate the Defense Department's reliance on foreign sources of critical materials.
Infinium said that its separation process uses clean technology as opposed to more traditional metal-making techniques used in China that have led to extensive health and safety concerns, environmental degradation and pollution.
