A Brief Introduction To Neodymium Magnets (NdFeB)
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.
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.

Coating for strong neodymium magnets
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.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.
Magnet Coating Types Display
Support all magnet plating , like Ni, Zn, Epoxy , Gold, Silver etc.
Ni Plating Maget: Good anti-oxidation effect, high gloss apprearance,long servie life .t
Application:
1). Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.;
2). Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;
3). Medical – MRI equipment and scanners;
4). Electronic product: keyboard, display, smart bracelet, computer, mobile phone, sensor, GPS locator,camera, audio, LED;
5). Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.
