　　since Sintered ferrite was developed in twentieth Century 60's. Sintered ferrite from Neodymium magnet factory is composed of the powder metallurgy process oxide materials. According to the difference in the molding process, can be divided into dry and wet ferrite magnet from Neodymium magnet factory. According to the internal structure of the data, it can be divided into anisotropic ferrite magnet and isotropic ferrite magnets from Neodymium magnet factory. It is believed to be the fundamental magnetic materials, it is widely used in many fields, because of its outstanding magnetic function, the material cost is low. In a variety of application, it can not be replaced, but in many new magnetic materials in recent years.

　　Permanent ferrite magnets from Neodymium magnet factory have excellent corrosion resistance, and has the ability of normal operation at -40 ° C and +250 ° C. As the temperature rises, the remanence decreases 0.2%/ ° C, the coercivity of adding 0.3%/ ° C. There is danger of permanent magnet demagnetization system operating point is low at very low temperatures.

　　SRO or BaO and Fe2O3 permanent magnet made of ferrite magnet, ceramic technology, now, we have the permanent magnetic products, 6 types of Y10T, Y20, Y25, Y30, Y30BH, Y35 and other commodities, including ring, disk, the blocks and segments.
