Detailed Product Description
Application: Electronics, Motors Composition: BaO·6Fe2O3, SrO·6Fe2O3
Product Type: Permanent Magnet

Hard Ferrite Magnet usually contains Barium ferrite (BaO · 6Fe2O3) and strontium ferrite (SrO · 6Fe2O3).  High resistivity is a semiconductor type, the eddy current loss, the coercive force can be effectively applied in the air gap of the magnetic circuit, is particularly suitable for small-scale generators and permanent magnet motors. It does not contain precious metals nickel, cobalt and other rich sources of raw materials, process is not complicated, low cost alternative to aluminum-nickel-cobalt permanent magnet. Its maximum energy product (B + H) m low, so in the case of equal magnetic energy larger than the volume of metal magnetic body. Its temperature stability is poor, brittle texture, fragile, impatient shock and vibration, are not suitable for precision measuring instruments and has required magnetic devices. The major products of anisotropic ferrite magnet series. They can be used for making permanent magnet ignition motors, permanent magnet motors, permanent magnet machine processing, permanent lifting head, a magnetic thrust bearing, the magnetic separator, a speaker, microwave devices, magnetic sheet, and hearing aids.
