Sintered SmCo Magnet
The SmCo permanent magnet has two types available: 1:5(SmCo5) & 2:17(Sm2Co17).
Samarium Cobalt (SmCo) magnets are manufactured by using powder metallurgy techniques which include stringent process controls and complicated heat treatment cycles. The composition of this alloy is approximately 35% Samarium, 60% Cobalt with the balance being Fe&Cu.
Application Fields:
All sorts of SmCo are used in the Electronic Magnetron, Magnetic Transmission, Magnetic Treatment, Magnistor, etc. And it’s mainly applications are servo-motors, pump coupling and sensors.
Advantages of SmCo Magnet:
1. Superior resistance to high temperature.
2. Excellent resistance to corrosion, no coating is needs for surface protecting.
3. High working temperature.
4. SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirement.
