Special Shaped SmCo Magnets

Irregular Shaped SmCo Magnets

Sintered magnets are produced via powder metallurgy process and generally criticized by their machinability, especially Samarium Cobalt SmCo magnets. SmCo magnets can be classified into 1:5 type SmCo magnets and 2:17 SmCo type magnets base on the alloy composition, then 1:5 type SmCo magnets and 2:17 type SmCo magnets are also known as as the first generation and second generation of rare earth permanent magnets, respectively. 1:5 type SmCo magnets have relatively better mechanical properties and malleability in comparison with 2:17 type SmCo magnets, then more easily to process micro SmCo magnets, thin-wall ring SmCo magnets, and special shaped SmCo magnets. SmCo magnets are still playing an irreplaceable role in higher temperature and high temperature stability areas which Neodymium magnets are not possible. Then miniaturization and functional complexity process of some certain application also generates large demands for special shaped SmCo magnets.
