What are the performance characteristics of the material of composite permanent magnets?

　　The material of composite permanent magnets is compounded by permanent magnetic material's powder and plastic material as a binder. Because it contains a certain proportion of binder, its magnetic energy is significantly reduced, compared with the corresponding magnetic materials without binder.

　　In addition to the metal composite permanent magnetic materials, because other composite permanent magnetic materials are affected by the binder heat resistance, its operating temperature is relatively low, generally not more than 150 ℃. But the composite permanent magnetic material‘s size precision is high, with good mechanical properties, the uniformity properties of permanent magnets are good, easy to magnet radial orientation and multipolar magnetizing.

　　Permanent magnets are mainly used in the manufacture of instrumentation, communications equipment, rotating machinery, magnetic therapy equipment and sporting goods.
