CMI scientists at Ames Laboratory, Lawrence Livermore National Laboratory, Oak Ridge National Laboratory and Eck Industries Inc. contributed to this research.

Achievement

  • Key commercial milestone passed: compositions of CMI’s Al-Ce based alloys have been accorded official designations by The Aluminum Association, opening the door to global industrial applications.
  • Received TechConnect 2019 Innovation Award in the TechConnect World Innovation Conference and Expo.

Significance and impact

  • Industry can now produce the alloys using the designations and invoking CMI commercialization
  • Based on its unique microstructure and resulting properties, the alloy has multiple energy-saving large-scale applications in transportation
  • Increased market demand for Ce will drive production of the critical rare earths needed for magnets
  • The AA designations require commercial transactions of feedstock and availability for sales in the marketplace, a milestone toward CMI’s moonshot in developing large-scale applications for Ce
