General Introduction of Sintered SmCo Magnet (Samarium Cobalt)
Sintered SmCo Magnet (SmCo magnets, magnetic rings, magnetic tiles, block magnets, magnetic cylinder, rare earth magnets, disc magnets,strong magnets, powerful magnets, permanent magnet). Sintered SmCo Magnet (SmCo Magnets) is biggest advantage is its high working temperature -350℃,in general ,magnetizing field of approximately 30 to 45 KOe are required. SmCo magnet is widely used in motors, meters, transducers, instruments, positional detector, generators , wind power generators, radar and other applications. We are professional Manufacturer of Sintered SmCo Magnet and SmCo Magnets in china.
