Anisotropic Samarium Cobalt Block Magnets Item NO. MPCO-SMBL series
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
350 Degree C High Working Temperature Permanent Rare Earth Magnets, sintered samarium cobalt blocks
