   Warmly welcome manufacturers and traders to visit our factory and establish business relationship.

SmCo magnets

SmCo magnets, made from cobalt and samarium and other rare-earth elements, is a high performance permanent magnet. Its biggest advantage is its high working temperature up to 300 degree centigrade. In the meantime, its higher corrosion and oxidation resistance are also crucial. So for SmCo magnets, it usually need not be plated with other metal and can be widely used in motors, watch, transducers, instruments, positional detector, generators, radar and etc..
