SmCo magnets have better temperature stability. SmCo magnets can be operated at higher temperature up to 300°C, while Nd-Fe-B magnets can not stand temperature over 200°C. Two types of SmCo magnets are SmCo5 and Sm2Co17.
The characteristics of Samarium Cobalt Magnet
*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
Attributes of Samarium Cobalt SmCo Sgment Magnets
*High resistance to demagnetization
*High energy (magnetic strength is strong for its size)
*Good temperature stability
*Expensive material (cobalt is market price sensitive)
