As the second generation of Rare Earth permanent magnet, SmCo not only has high energy ranging from 14MGOe to 28MGOe and reliable coercive force, but also exhibits the best temperature characteristics in Rare Earth material family Compared with NdFeB, SmCo are suitable for working higher temperature. SmCo includes rare earth Sm1Co5 and Sm2Co17 and are referred to as 1:5 and 2:17 materials
Attributes of Samarium Cobalt
· High resistance to demagnetization
· High energy (magnetic strength is strong for its size)
· Good temperature stability
· Expensive material (cobalt is market price sensitive)
It needn' t to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch, transducers, instruments, positional detector, generators, radar, and etc.
Features:
Features:
1. High energy product
2. Excellent coercive force
3. Stable against temperature change
4. Good resistance to demagnetization, stability in high temperatures and excellent conduction, as well as allow unique design
5. Higher corrosion
6. Raw material sm is low, so the price for smco magnets are very high.
APPLICATION:
aerospace, defense industry, microwave devices, communications, medical equipment, instruments, wind power, a variety of magnetic drives, sensors, magnetic processor, high-end motor, etc.
