Applications of Samarium Cobalt Magnets
- Computer disc drives
- Sensors
- Traveling wave tubes
- Linear actuators
- Satellite systems
- Motors where temporary stability is vital
Attributes of Samarium Cobalt Material
- High resistance to demagnetization
- High energy (magnetic strength is strong for its size)
- Good temperature stability
- Expensive material (cobalt is market price sensitive)
