Property introduction
Our company has committed to tool high-hardness materials on miro-precision scale by high-precision modern processing techniques, with different shapes such as cylinder, ring, square, round, U-shape, T-shape etc. available at our end. 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℃). 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.
