Generally, the bonded magnet is produced by molding compression of the compound alloy powder with epoxy resin。It also can be made by injection or extrusion from alloy powder mixing with plastic. The characteristics as follows:

1、Higher magnetic property: the magnetic property of bonded magnet is between that of sintered magnet and ferrite, and with good consistency and stability.

 2、Large freeness of product shapes and high-precision dimension: the magnet shape and dimension can be shaped as an annulus, tile, blocks etc., without further sintering and mechanical processing.

3、Good corrosion resistance: after ED coating or some special treatments, the magnet can be used under normal or unfavorable environmental conditions for a long time.

4、Multifarious magnetization: multi-pole magnetization and screw angle magnetization are available, and the field distribution could be squared, sinusoid etc.

5、It is suitable for mass production with high efficiency.

The bonded magnet is mainly used for all kinds of small and micro-motors, such as spindle motor, stepping motor, synchronous motor, DC motor and brushless DC motor. It can replace sintered magnet and ferrite, making motor assembling easier and more reliable, reducing costs and improving efficiency.
