The main raw material of sintered ferrite is iron oxide, so it will not be corroded by high temperature, high humidity or chemicals (except strong acids and alkalis); sintered ferrite mainly includes barium ferrite (BaO•6Fe2O3) and strontium Ferrite (SrO•6Fe2O3) two types; sintered ferrite is divided into isotropic and anisotropic. Isotropic sintered ferrite has weak magnetic properties, has the same magnetic properties in any direction, and can be multi-pole magnetized in any direction; anisotropic sintered ferrite has higher magnetic properties than isotropic and can only be shaped Magnetization in the direction of magnetic field orientation;

Sintered ferrite has excellent demagnetization resistance and no magnetic flux loss before and after assembly and magnetization; the operating temperature of sintered ferrite is -40°C to +250°C.
