Rare Earth Smco Magnet
General Description
1. Material:30%Samarium, 60% cobalt with the balance being Fe & Cu.
2. Shape:Arc,Block,Ring
3. Application: motors, watch, transducers, instruments, positional detector,ingenerators, radar and other applications.
4. Super high working temperature, high performance, strong anticorrosion, high precision of all sizes. Excellent resistance to corrosion, no coating is needed for the surface protecting.
5. Samarium Cobalt magnet has superior resistance to high temperature (Max Temperature reaches 350 degree centigrade). When working at above 180 degree centigrade, its maximum energy product BH and temperature stability are superior than NdFeB Magnet.
