SmCo magnet
Samarium-cobalt magnets are primarily composed of samarium and cobalt. They have been available since the early 1970s. This type of rare-earth magnet is very powerful, however they are brittle and prone to cracking and chipping. Samarium-cobalt magnets have Maximum Energy Products (BHmax) that range from 16 Mega-Gauss Oersteds (MGOe) to 32 MGOe, their theoretical limit is 34 MGOe. Samarium Cobalt magnets are available in two "series", namely Series 1:5 and Series 2:17.
Smco magnets withhigh performance, low termperature coefficent perament magnet made of Samarium and cobalt and other rare-earth elements. The biggest advantage is high working temperature--350 degree centigrade. There is no need to be coated because it is difficult to be eroded and oxidized. SmCo magnets are widel used in motors, watch, transducers, instruments, positional detector, generators, radar and etc.
Samarium Cobalt (SmCo) magnets, of the Rare Earth class, have been available since the early 1970's. These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion. These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and environments.
SmCo magnets are manufactured by sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30 to 45KOe are required to saturate SmCo magnets.
Key application:
- The characteristics of Samarium Cobalt Magnet
- Very high magnetic properties with good stability.
- Superior resistance to high temperature,Curie temperature of majority is over 800
- Excellent corrosion resistance capability,no coating is needed for surface protection
