Smco magnet, is a kind of rare earth magnets,samarium, cobalt and other rare earth metal materials by a certain proportion, melting into the alloy, through crushing, pressing, sintering a magnetic material. SmCO5 & Sm2Co17. Working temperature:250?,350?. High magnetic energy product, high temperature resistant, the highest working temperature can reach 350 ?, low temperature, unlimited in operating temperature above 180 ?, the maximum magnetic energy product (BHmax), coercive force (coercivity), temperature stability and chemical stability than ndfeb permanent magnet.
