Rare Earth Magnet (SM-CO)
Product ID: 12
SmCo magnet is a high performance low temperature coefficient permanent magnet made of samarium and cobalt and other rare earth elements. This type of magnet possesses strong magnetic and coercive force, high resistance to corrosion and high working temperature 350 degree centigrade. SmCo magnet is widely used in Headphone, Speakers, Watch, Transducers, Motors, generators and radar etc...
