SmCo magnet is a high performance low temperature coefficient permanent magnet made of samarium and cobalt and other rare earth elements. Sm-Co magnets can be operated at higher temperature up to 300centigrade degree...Sm-Co materials come in energy products from 16 MGOe up to 33 MGOe. Their high resistance to demagnetizing influences and excellent thermal stability has ensured Sm-Co as the premium choice for the most demanding motor applications.

Advantage
1)Excellent thermal stability
2)High magnetic properties
3)Good corrosion resistance
4)High resistance to demagnetization

Disadvantage
1)Difficult to machine
2)Expensive material (cobalt is market price sensitive)

Application of Samarium Cobalt Magnets
1)Sensors
2)Magnetic couplings
3)High performance motors
4)Magnetic separators
