NdFeB magnet: NdFeB is the magnet with the highest commercial performance found at present, which is called magneto. It has extremely high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than Ferrite (Ferrite). Therefore, it is also commonly known as: strong magnetic, magnetic steel, etc. Its own mechanical processing performance is also quite good. The working temperature can reach up to 200 degrees Celsius. And its texture is hard, its performance is stable, and it has good cost performance, so it is widely used. But because of its strong chemical activity, its surface layer must be treated.

   NdFeB permanent magnet material is a permanent magnet material based on intermetallic compound Nd2Fe14B. Compared with casting Al-Ni-Co series permanent magnet materials and Ferrite Permanent Magnet Materials, NdFeB has extremely high magnetic energy product and coercive force, and can absorb 640 times of its own weight. The advantage of high energy density makes NdFeB permanent magnet materials widely used in modern industry and electronic technology, thus making instruments, electroacoustic motors, magnetic separation magnetization and other equipment small, lightweight, thin becomes possible. Material characteristics NdFeB has the advantages of high performance-price ratio, good mechanical characteristics and easy cutting and processing. The disadvantage lies in low Curie temperature point, poor temperature characteristics and easy pulverization and corrosion, only by adjusting its chemical composition and adopting surface treatment methods can it be improved to meet the requirements of practical application.
  Manufacturing process NdFeB is manufactured by powder metallurgy, which will contain a certain proportion of raw materials such as neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, copper, boron and iron are smelted into medium frequency induction melting furnace by alloy steel ingot, then broken into 3 ~ 5cm powder, and pressed and formed in magnetic field. The formed green body is sintered in vacuum sintering furnace and tempered for aging, in this way, a permanent magnet blank with certain magnetic properties is obtained. After grinding, drilling, slicing and other processing procedures, the finished NdFeB product required by users is obtained after surface treatment.
