- The neodymium iron boron permanent magnet is made of neodymium, iron and boron. It is a intermetallic compound Nd2Fe14B crystal structure. Its feature is high magnetic energy product and high coercive force. Normally it only have three kinds of the neodymium iron boron permanent magnet, sinter, bond, hot press. Normally sintered magnet need surface coating to corrosion resistance. Bond magnet isotropy magnetization. Adding dysprosium could adjust the magnet performance.
- Neodymium iron boron permanent magnet is a kind of the Neodymium iron boron magnetic material. The sintered neodymium iron boron permanent magnet is the best material. The sintered magnet has high magnetic energy product, high coercivity and high density. These make the sinter magnet are widely used in modern industry, electronic technology and medical industry. The instrument and apparatus, motor, medical equipment smarter, light weight and intelligent.
- The advantage of the magnet is high magnetic energy product and high coercivity, it could be machined into different shapes by different processing technology. The disadvantage is the low curie temperature, easy to corrosion. It must be coating using chemical treatment to make the magnet anti corrosion.
- The magnet could be divided into sinter and bond. The bond magnet has magnetism into every directions, anti corrosion. The sinter magnet could be easily corrosion. Normally it needs surface coating, eg. zinc coating, nickel coating, gold coating and so on.
