1. Alnico magnets are alloys of aluminum, nickel, cobalt, iron and other trace metals. The casting process can be processed into different sizes and shapes, and the processability is very good. Powerful magnet cast AlNiCo permanent magnets have the lowest reversible temperature coefficient and can operate at temperatures above 600 degrees Celsius. AlNiCo permanent magnet products are widely used in a variety of instrumentation and other applications.

2. NdFeB magnet It is the magnet with the highest commercial performance. It is called magnetic king and has a very high magnetic performance. Its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. The mechanical properties of the magnetic steel itself are also quite good. Operating temperatures up to 200 degrees Celsius. The powerful magnet has a hard texture, stable performance and good cost performance, so it is extremely widely used. However, because of its strong chemical activity, the magnet must be coated on its surface. (such as Zn, Ni, electrophoresis, passivation, etc.).

3. Samarium Cobalt (SmCo) is classified into SmCo5 and Sm2Co17 depending on the composition. Its development is limited due to the high price of its materials. Samarium Cobalt (SmCo), as a rare earth permanent magnet, not only has a high magnetic energy product (14-28 MGOe), reliable coercivity and good temperature characteristics. Compared with neodymium iron boron magnets, samarium cobalt magnets are more suitable for working in high temperature environments.

4. Ferrite magnets Its main raw materials include BaFe12O19 and SrFe12O19. The powerful magnet is made by the ceramic process, and the texture is relatively hard. It is a brittle material. Since the ferrite magnet has good temperature resistance, low price and moderate performance, it has become the most widely used permanent magnet.
