General Introduction

Samarium cobalt (Samarium Kobalt) is a high performance, low temperature coefficient permanent magnet with its high working temperature—350 degree centigrade. When working above 180 degree centigrade, Samarium cobalt (Samarium Kobalt) maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. Samarium cobalt (Samarium Kobalt) needn’t to be coated because it is difficult to be eroded and oxidized. Samarium cobalt (Samarium Kobalt) is widely used in motors, watch, transducers, instruments, positional detector, generators, radar communications, medical equipments, various magnetism spreading devices, magnetic processor, electrical engineering and magnetic derrick.
