SmCo Magnets

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 300��C. 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 

• Excellent thermal stability
• High magnetic properties
• Good corrosion resistance
• High resistance to demagnetization

Disadvantage

• Difficult to machine
• Expensive material (cobalt is market price sensitive)

Application of Samarium Cobalt Magnets

• Sensors
• Magnetic couplings
• High performance motors
• Magnetic separators
