1. Made of Sm,Co, Fe and other rare-earth elements.
2. Samarium cobalt magnets will produce to all kinds of shape, there are disc, ring, cube, fan-shaped, arc-segment and others etc.
3. With highest remanence and the highest temperature stability, maximum operating temperature up to 250～350°C.
4. Samarium cobalt generally do not need surface treatment for its strong corrosion resistance.
5. Samarium cobalt magnets are suitable for producing high-performance motors and complex working environment, with highest magnetic performance and good stability.
We would like to provide technical support and solve the technical problems when customer are in application and design project.
