Sintered NdFeB permanent magnet material is based on the intermetallic compound Nd2Fe14B, the main components are neodymium, iron, and boron. In order to get different magnetic properties, a part of neodymium can be replaced by other rare earth metals such as dysprosium and praseodymium, and a part of iron can be replaced by other metals such as cobalt and aluminum. The compound has a tetragonal crystal structure, with high saturation magnetization strength and uniaxial anisotropy field, which is the main source of the properties of NdFeB permanent magnets.
NdFeB magnet is a kind of rare earth permanent magnet. In fact, this kind of magnet should be called rare earth iron boron magnet, because this kind of magnet uses more rare earth elements than just neodymium. But it is easier for people to accept the name NdFeB, it is easy to understand and spread. There are three kinds of rare earth permanent magnets, divided into three structures RECo5, RE2Co17, and REFeB. NdFeB magnet is the REFeB, the RE are the rare earth elements.

NdFeB Magnet Coating and Plating
Sintered NdFeB has the strongest magnetic properties, but it has one of its biggest weaknesses, its corrosion resistance is too poor, so sintered NdFeB needs to be plated.
NdFeB plating process usually includes oil removal, water washing, ultrasonic pickling, ultrasonic water washing, soaking in MJ670 passivation solution, then many times water washing, then nickel or zinc t plating, etc. Among them, passivation sealing treatment is an important role in NdFeB plating. Because the production process of sintered NdFeB is a powder metallurgy process, there will be small pores on the surface of the product. To make the plating layer more dense and improve the corrosion resistance, the passivation sealing treatment before plating is very important.

Warning：
1. Neodymium iron boron magnets are hard and brittle. They are fragile products. When separating the magnets, please move and stagger them carefully. Please do not break them directly. After separating, please keep a certain distance to avoid hand clamping. Special attention must be paid to magnets with strong suction and large size. Improper operation may crush the finger bones.
2. Please keep the strong magnet out of the reach of children to avoid swallowing, because children may swallow the small magnet. If the small magnet is swallowed, it may be stuck in the intestinal tract and cause dangerous complications.Magnets are not toys! Make sure children do not play with magnets.
3. Magnets are made of different metals and have the function of conducting electricity. A child may try to insert a magnet into a power outlet and get an electric shock.
