SmCo Magnets

Product Detailed

SmCo magnet is a high performance, low temperature coefficient permanent magnet made of samarium and cobalt and other rare-earth elements. Its biggest advantage is its high working temperature---350℃,in general ,magnetizing field of approximately 30 to 45 KOe are required. 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 and other applications.
