    ), and RE2TM14B. Rare earth magnets are known for their superior magneticproperties-high induction, and coercive force. These properties arise due to the extremely highmagnetocrystalline anisotropy made possible by unique 3d-4f interactions between transitionmetals and rare earths. For more than 40

  • Designing with High Performance Rare Earth Permanent Magnets
    Rare earth permanent magnets have the widest range of magnetic properties and are used in anextensive variety of applications. Sintered NdFeB magnets have the highest maximum energy product (BH)maxbut are limited to applications with relatively low temperatures. Sintered Sm2Co17-type magnets have
  • Permanent Magnet Material
    . The permanent magnet family consists, in general terms, of non-rare earth permanent magnets and rare earth magnets. The non-rare earth magnets include Alnico (Aluminum-Nickel-Cobalt) magnets and Ceramic (Strontium and Barium Ferrite) magnets. Rare earth magnets include Sm-Co (Samarium-Cobalt) magnets

    Rare earth permanent magnets have the widest range of magnetic properties and are used in anextensive variety of applications. Sintered NdFeB magnets have the highest maximum energy product (BH)maxbut are limited to applications with relatively low temperatures. Sintered Sm2Co17-type magnets have
  • HIGH PERFORMANCE MAGNET MATERIALS: RISKY SUPPLY CHAIN
    Today, nearly 100% of the world's rare earthmetals and over 94% of rare earth oxides comefrom China. This dominance has become un-mistakable during the past decade, and has been accompanied by a steep decline in U.S.production capabilities. It is most notable in theNdFeB (neodymium-iron-boron
  • Sm-Co and Pr-Fe-B Magnets with Increased Electrical Resistivity
    , but the residual inductionwas decreased due to a lower density.Fully dense composite magnets based on Pr-Fe-B and other rare earth fluoride powders were produced by hot pressing and die upsetting the precursor blends. The overstoichiometriccomposition of Pr 14.5Fe79.5B6powders from melt-spun precursors allowed
