Special Shaped SmCo Magnets

Sintered magnets are produced via powder metallurgy process and generally criticized by their machinability, especially sintered Samarium Cobalt magnets. Sintered SmCo magnets can be classified into 1:5 type Samarium Cobalt magnets and 2:17 Samarium Cobalt type magnets base on the alloy composition, then 1:5 type and 2:17 type 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 compared with 2:17 type SmCo magnets, then more easily to process SmCo micro magnet, thin-wall ring SmCo magnet, and special shaped SmCo magnet. Sintered SmCo magnets are still playing an irreplaceable role in higher temperature and high temperature stability areas which sintered Neodymium magnets are not possible. Then miniaturization and functional complexity process of some certain application also generates large demands for special shaped SmCo magnet.

SmCo magnet is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo permanent magnetic iron and rare-earth cobalt permanent magnet. It is a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior NdFeB magnetic materials. It needn’t to be coated because it is difficult to be eroded and oxidized.

Application field
The SmCo magnet is widely used in motors, watch, transducers, instruments, positional detector, generators, radar communications, medical equipments, various magnetism spreading devices, magnetic processor, electrical engineering and magnetic derrick. The Smco permanent magnet can be used in high-temperature, high-humidity and corrosive environment.
