The sintered NdFeB permanent magnet material is based on the intermetallic compound ND2FE14B.

　　The main components are rare earth (Nd), iron (Fe), and boron (B).

　　In order to obtain different properties, rare earth Nd can be replaced with some rare earth metals such as dysprosium (Dy) and praseodymium (Pr).

　　Iron can also be partially replaced by other metals such as cobalt (Co), aluminum (Al), the content of boron is small,
 

　　But the degree plays an important role in the formation of tetragonal crystal structure intermetallic compounds

　　Makes the compound have high saturation magnetization, higher uniaxial anisotropy and higher Curie temperature.

　　NdFeB raw materials contain what ingredients

　　Different grades may use different metal elements, the overall overview of the metal elements used are:

　　Praseodymium, neodymium, dysprosium, holmium, gadolinium, boron, aluminum, copper, cobalt, niobium, neodymium, samarium, terbium, zirconium, iron, gallium, titanium, cerium
