Sintered SmCo
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 Samarium Cobalt Magnet ¡®s 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.
