Deep-hole thin wall ring SmCo magnet,ceramic magnet,The specific shape and size can be available by producing according to different drawing designs from customers. The various magnets can be widely used to make into super hard micro magnetic precision parts for timekeeper, micro-motor, optical communication electronics, electro-acoustics, digital camera etc. 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.
