Permanent ferrite magnet, also known as hard magnet, is a non-metallic magnetic material.In 1930, Kato and Wujing discovered a kind of spinel (MgA12O4) permanent magnet, which is the prototype of ferrite widely used today.Ferrite magnet are mainly made of SrO or Bao and Fe2O3 as raw materials by ceramic process (pre firing, crushing, pulverizing, pressing, sintering and grinding). It has the characteristics of wide hysteresis loop, high coercive force and high remanence. It is a kind of functional material that can keep constant magnetism once magnetized. Its density is 4.8g/cm3. According to different production processes, ferrite magnet can be divided into two types: sintering and bonding. Sintering can be divided into dry pressing and wet pressing, and bonding can be divided into extrusion, compression and injection molding. The soft, elastic and twisted magnet made of bonded ferrite powder and synthetic rubber is also called rubber magnet. According to whether the external magnetic field is applied or not, it can be divided into isotropic permanent magnet and anisotropic permanent magnet.

Compare with other magnetic materials

Advantage: Low price, wide source of raw materials, high temperature resistance (up to 250 ℃) and corrosion resistance.

Disadvantage: Compared with NdFeB products, its remanence is very low. In addition, due to the relatively loose and fragile structure of its low density material, many processing methods are limited by it, such as punching, digging, etc., the majority of its product shape can only be pressed by the mold, the product tolerance accuracy is poor, and the mold cost is high.

Coating: Due to its excellent corrosion resistance, it does not need coating protection.
