Permanent Rare Earth-Iron-Boron (RE-Fe-B) powders are largely based upon Nd-Fe-B or Nd-Pr-Fe-B alloy compositions for the manufacture of bonded magnets. They are produced by Molycorp Magnequench by employing a proprietary rapid solidification process followed by a milling process and heat treatment.
By substituting iron and/or rare earth materials with other specific elements, both magnetic and mechanical properties can be tailored to specific application requirements.
Certain compositions are designed to include lower cost rare earth materials like Lanthanum and Cerium, which are well-suited for cost sensitive applications.
