NioCorp Developments reports the successful production of an aluminum-scandium (AlSc) master alloy using a new metallurgical process.
NioCorp Developments (TSX:NB,OTCQX:NIOBF) reports the successful production of an aluminum-scandium (AlSc) master alloy using a metallurgical process. The production of the alloy evidences that there is a commercial pathway to potential production of the master alloy.
As quoted from the press release:
The AlSc master alloy was produced at Ames Laboratory’s Materials Preparation Center, located in Ames, Iowa, under the supervision of NioCorp engineers and employing an improved production methodology specified by Tactical Alloys, a firm with over 20 years of experience in the AlSc alloy space. Ames Laboratory is a U.S. Department of Energy national laboratory recognized as a world leader in the research and development of rare earth and rare metal materials, such as scandium. NioCorp commercially purchased the scandium used to create the master alloy at Ames Laboratory’s Materials Preparation Center.
AlSc master alloys are used to introduce scandium into final casting-type and wrought-type aluminum-based alloy melts. Even a small amount of scandium can provide multiple benefits to aluminum alloys, including grain refinement during casting and solidification; improved weldability for minimizing weld cracks and failures; and increased yield and tensile strength of the alloy, which in turn can reduce the mass (weight) of platforms such as aerospace systems, cars, trucks, and buses, thus increasing fuel economy and reducing air emissions.
The recent alloy production was the second such AlSc master alloy production test run performed by NioCorp and researchers at Ames Laboratory’s Materials Preparation Center. NioCorp is currently developing its proposed Elk Creek Superalloy Materials Facility in southeast Nebraska, which is expected to produce approximately 95 tonnes of Scandium Trioxide annually once it is constructed and enters commercial operation, according to the Company’s April 2019 Elk Creek Project Feasibility Study. Current global production and consumption of scandium are estimated by the U.S. Geological Service (“USGS”) to be approximately 10-15 tonnes per year, most of which is believed to be produced in China.
