Bonded Ferrite Magnet
Bonded Ferrite MagnetBonded Ferrite magnet is made by mixing the ferrite powder with polymer plastic (such as PA,Website:, PPS, etc.,), then through the mold to inject the various magnet shapes. Applying the magnetic field orientation, we can get the anisotropic magnets. With the rapid development of electronic information technology, the market for magnetic materials and magnetic components in complex shape, size precision, miniaturization, lightweight, intelligent, and the overall shape and put forward higher requirements for the powder injection molding technology in permanent magnet industry provides enormous opportunities, the market for injection ferrite magnets will be bigger and bigger.With the following characteristics:1. Can be magnetized in aby direction, suitable for the radial or axial (face) multi-poar magnetized magnet.2. One time forming the complex shape.3. Forming the shape with the shaft or bushings one time to reduce assembly processes and improve assembly accuracy.4. No aurface treatment.Magnetic properties and physical parameters of injection ferrite:GradeBrHcbHcj(BH)maxRecoil temperature coefficient of B
