Ferrite divided barium ferrite (BaO · 6Fe2O3) and strontium ferrite (SrO · 6Fe2O3). High resistivity, is a semiconductor type, so a small eddy current losses, the coercive force, not the merits of demagnetization can be effectively applied in the air gap in the magnetic circuit, particularly suitable for small generators and permanent magnet motors.
The major products anisotropic ferrite permanent magnet series. They can be used to make the permanent ignition motors, permanent magnet motors, permanent magnet concentrator, magnetic lifting heads, magnetic thrust bearing, magnetic separator, speakers, microwave devices, magnetic sheet, and hearing aids.
