SmCo magnet is also named with SoCo magnetic steel, SmCo permanent magnet, SoCo 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 prodcut BH and steady temperature are superior than NdFeB magnetic material. It needn't to be coated because it is difficult to be eroded and oxidized.

SmCo block magnets widely used in pump couplings, vairous magnetism spreading devices and so on.
