Samarium
Cobalt magnets are high performance energy
products ranging to 32MGOe. SmCo magnets are better able
to withstand higher temperatures than other rare earth
magnets. 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 degree centigrade.
It needn't to be coated because it is difficult to be
eroded and oxidized.
