NCMag™ supplier of super mini rare earth(SmCo,NdFeB)cylinder magnets; manufacturer of micro ring neodymium or ferrit disc magnets in china.

what's micro ring magnet(SmCo, NdFeB, ferrit)? where's miniature neodymium disc magnets manufacturer? how to buy small samarium cobalt block magnets or mini ceramic magnets?

We offer a wide variety of micro magnet products and services. We are good at micro magnet, normly very small and precise magnets. We can supply Alnico, NdFeB, SmCo, ferrite and other materials with very good tolerances. The size(diameter or length) could be at 0.1-10mm, and the tolerance could be +/-0.005~+/-0.02mm with various shapes.

high-temp resistant ring magnet for mobile phone, vibration motor. It is applicable for mobile phone, vibration motor featuring high-temp resistance, with high-temp resistant and corosion resistant Sm2Co17 as raw material, can be tooled according to customers’s drawings, have been applied to many famous brands of mobile phones based on a batch quantity. We are specialized in precision machining of magnets. 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. 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.
