returnSmCo
SmCo Magnet (Sintered SmCo Magnet) is a high performance, low temperature coefficient permanent magnet with its high working temperature – 350 degree centigrade. When working above 180 degree centigrade, SmCo Magnet (Sintered SmCo Magnet) maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. SmCo Magnet (Sintered SmCo Magnet) needn’t to be coated because it is difficult to be eroded and oxidized.
Sintered SmCo 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.
