Property introduction

We are specialized in precision machining of super hard materials, esp. in micro-appliances including deep-hole thin wall ring magnet elements, enjoying a high competitiveness within market both at home and abroad.The specific shape and size can be available by producing according to different drawing designs from customers. The various magnet can be widely used to make into super hard micro magnetic precision parts for timekeeper, micro-motor, optical communication electronics, electroacoustics, digital camera etc.SmCo magnet is a kind of permanent magnet mainly made of RE samarium, metal Cobalt and other elements.It features high energy product, very low temperature coefficient, and a relatively stable magnetic property under high temperature(with max temperature up to 350°C). Besides, with strong anti-corrosion resistance, generally it doesn’t need any electroplating at all, it can widely applied in motor, meter, sensor, radar, magnetic drive and other high-tech areas.
