The Samarium Cobalt magnets produced by Hangzhou Vast Precision Technology have high temperature resistance up to 350° and 500°, the highest magnetic property Br＞1.17T, and the magnetic property can be more than the sintered NdFeB in the case of the long time working temperature is more than 150 degrees. The main advantages of samarium cobalt magnets are: high temperature resistance, stable magnetic properties, corrosion resistance, no electroplating in general, high dimensional accuracy, magnetic declination can be controlled within 1°.
