Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
Characteristic of SmCo Magnet as follows:
High resistance to demagnetization
High Energy Product
Good temperature stability
High resistance of corrosion and oxidation
Expensive material (cobalt is market price sensitive)
Application: aerospace defense military microwave devices communication medical equipment instruments, all kinds of magnetic transmission device, sensor, a magnetic processor, electrical, magnetic force crane
