The 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℃,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.
