Product Introduction
There are two major types of SmCo magnets available, 1:5 type (SmCo5) and 2:17 type (Sm2Co17). SmCo magnets have very high magnetic properties and temperature properties. Their Curie temperature can be as high as 710 to 880 °C Maximum working temperature usually in a range of 250 to 350 °C As a result, this kind of magnets has the best magnetic stability.
SmCo magnets have very good corrosion resistance capability, so no coating is needed for surface protection.
Characteristics
- Very high magnetic properties with good stability
- Superior resistance to high temperature. Curie temperature of majority is over 800.C
- Excellent corrosion resistance capability, no coating is needed for surface protection
