Detailed information

The main raw material of sintered ferrite is orthoferrite, so it cannot be corroded by high temperature, high humidity or chemical substances (except strong acid and alkali);

Sintered ferrites mainly include barium ferrite (BaO•6Fe2O3) and strontium ferrite (SrO•6Fe2O3);

Sintered ferrites are also classified into isotropic and anisotropic..


Property:

The magnetic property of isotropic sintered ferrite is weaker relatively, it 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 magnetized in the direction of magnetic field orientation during molding;

Sintered ferrite has excellent demagnetization impedance and no flux loss before and after assembly and magnetization;

The working temperature of sintered ferrite is -40 ° C to + 250 ° C, the temperature coefficient is poor, and the temperature coefficient of Br is -0.2% / ° C, that is, when temperature increases 1°C, Br decreases by 0.2%.


Application fields:

A large quantity of sintered ferrites is applied in permanent magnet motor, DC motor, speaker, reed switch, magnetic separator and sucking devices, etc.
