1.SmCo magnets :
SmCo magnets are high performance, low temperature coefficient rare earth permanent magnets, and could keep their performance under the maximum working temperature 350 degree centigrade. SmCo Magnets are composed of Samarium, Cobalt, and a few transition metals.
2.Species : smCo Magnets--- typical divided into two material series, SmCo 1: 5 and of SmCo 2: 17.
3.Main Application of SmCo Magnets: Motors, Sensors, Transducers, Generators, Radar, Linear actuators, Satellite systems etc.
4.SmCo Magnets have following advantages:
1. Possess strong magnetic properties - 5-7 times more powerful than ferrite.
2. A good stability of ultra-high magnetic.
3. Better resistant to high temperatures, most of the Curie temperature above 800 c
4. Excellent corrosion resistance capability, no coating is needed for surface protection.
