Injection ferrite is a kind of injection magnet made by mixing permanent magnet ferrite and polymer resin. In terms of electrical characteristics, the resistivity of injection ferrite is much greater than that of metal, alloy magnetic material, and injection NdFeB material. Injection ferrite also has higher dielectric properties.
The advantages of injection NdFeB are high-cost performance, high corrosion resistance compared with sintered magnetic, good mechanical properties, etc.
1. The magnet in injection ferrite is not as good as injection NdFeB.
2. The price of injection ferrite is much cheaper than that of injection NdFeB magnet.
3. Injection ferrite is stable, and it is oxide which is very stable.
For mechanical properties, injection magnet is not easy to break, because there is polymer resin in the composition, and sintered magnetic is easy to fracture with unfilled corner.
