SmCo is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo
permanent magnetic iron and rare-earth cobalt permanent magnet. It’s 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 than NdFeB magnetic materials. It needn’t to be coated because it is difficult to be eroded and oxidized. 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,Samarium Cobalt holds its standard property in higher maximum temperatures than  Neodymium,although its maximum strength is less. The cost of SmCo material is the most expensive,so SmCo is recommended only when its performance is a high temperature environment is a concern.

The characteristics of Samarium Cobalt Magnet

*Very high magnetic properties with good stability.

*Superior resistance to high temperature, Curie temperature of majority is over 800℃

*Excellent corrosion resistance capability, no coating is needed for surface protection
