Sintered Ferrite
| Sintered Ferrite Magnet was developed since 1950s. It is manufactured from Oxide material by Powder metallurgical process. According to the difference in molding process, it can be divided into Dry Type and Wet Type ferrite magnets. According to the inner structure of the material, it can be divided into Anisotropic Ferrite Magnet and Isotropic Ferrite Magnet. It is considered a fundamental magnetic material, for it is widely used in many fields owing to its |

good magnetic performance and the low cost of its raw material. In various applications, it can not be replaced, although many new magnetic materials came out in recent years |
