Sintered Ferrite will not be corroded even in high-temperature, high-humiditity,  high-salt-spray applications. It also has good chemical stability;

The sintered Ferrite have mainly two types:Barium Ferrite(BaO•6Fe2O3) and Strontium Ferrite (SrO•6Fe2O3);

The sintered ferrite magnets are available in isotropic magnet and anisotropic magnets.

Property：

Isotropic ferrite magnets’ magnetic properties are low ，they have nearly the same magnetic properties in all directions ，can be magnetized in many different directionsin multi-poles;

Anisotropic Ferrite magnets have higher magnetic properties compare with isotropic ferrite magnet. However, this type of magnets can only be magnetized along a preferred direction;

The sintered Ferrite has an excellent resistance to demagnetization and can be magnetized beforeafter assembly without danger of losing any property;

The sintered Ferrite can be used in operating temperatures ranging from -40°C to + 250°C， have a poor temperature coefficient，Br temperature coefficient is -0.2%/℃，The Br losing is approximately 0.2% when temperature is Increased by 1℃;

Application field：

The applications include permanent magnet motor, DC motors, loudspeakers, reed switch operation, magnetic separator assemblies and general holding devices etc.
