SAMARİUM COBALT MAGNETS

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.
