Samarium Cobalt magnet has superior resistance to high temperature(max temp reaches 350 degree centigrade).When working at above 180 degree centigrade, its maximum energy product BH and temperature stability are superior than NdFeB magnet. It needn't to be coated because it is difficult to be eroded and oxidized
Applications: Motors, Sensors, Transducers, Generators, Radar, Linear actuators, Satellite systems etc.
