Permanent Magnetic Ferrite Material

  Permanent magnetic ferrite material

  1. NdFeB Magnet It is the magnet that has been found to have the highest commercial performance. It is called magnetic king and has a high magnetic property with a maximum magnetic energy product (BHmax) of more than 10 times higher than that of Ferrite. Its own mechanical processing performance is also quite good. Operating temperature up to 200 degrees Celsius. And its texture is hard, stable performance, a very good price, so its application is extremely extensive. But because of its strong chemical activity,Permanent magnetic ferrite it must be its surface coating treatment. (Such as plating Zn, Ni, electrophoresis, passivation, etc.).

  2. Ferrite Magnets Its main raw materials include BaFe12O19 and SrFe12O19. Made of ceramic technology, the texture is relatively hard, is a brittle material, because the ferrite magnets have good temperature resistance, low price, moderate performance, has become the most widely used permanent magnet.

  3. Alnico is a kind of alloy composed of aluminum, nickel, cobalt,Permanent magnetic ferrite iron and other trace metal elements. The casting process can be processed to produce different sizes and shapes, and the workability is excellent. Cast aluminum nickel cobalt permanent magnet has a minimum reversible temperature coefficient, the working temperature can be as high as 600 degrees Celsius. Alnico permanent magnet products are widely used in a variety of instrumentation and other applications.

  4. SmCo (SmCo) is divided into SmCo5 and Sm2Co17 depending on the composition.Permanent magnetic ferrite Due to its material price is expensive and its development is limited. SmCo (SmCo) as a rare earth permanent magnet, not only has a high energy product (14-28MGOe), reliable coercivity and good temperature characteristics. Compared with NdFeB magnets, samarium cobalt magnets are more suitable for working in high temperature environments.
