Samarium Cobalt Ring Magnets provide a great value because not only are they very strong, but they resist both corrosion and temperature very well. They do not require any coating. For a magnet that seems to have it all, the only drawback is that they are the most expensive to produce.
These magnets are often used in:
- High performance motors
- Magnetic couplings
- Magnetic separators
Samarium Cobalt magnets can crack and chip since they are brittle. They can be used for applications that require high temperatures, when neodymium magnets will not work. They are also resistant to corrosion, resistant to demagnetization and they provide good thermal stability.
