Description

CERAMIC MAGNETS

Hard Ferrite Ceramic magnet is a permanent magnet mainly made of SrO or BaO and Fe2O3. Compared with other permanent magnets, ferrite magnets are hard, brittle and have low magnetic energy. However, it is not easy to demagnetize and corrode. The production process is simple and the price is low. Therefore, ferrite magnets have the highest output in the entire magnet industry and are widely used in industrial production.

Hard ferrite magnet is not mixed with metals such as nickel and diamond. It has high resistivity and large coercivity. It can be effectively used in large-gap magnetic circuits and is especially suitable as permanent magnets for small generators and motors.
