What are the components of neodymium magnets? What is the proportion?
NdFeB permanent magnet material is a permanent magnet material based on intermetallic compound ND2FE14B. The main components are rare earth (ND), iron (FE), boron (B). In order to obtain different properties, the rare earth ND can be replaced by some other rare earth metals such as dysprosium (Dy), praseodymium (Pr), iron can also be replaced by other metals such as cobalt (Co), aluminum (Al), etc. The content of boron is small, but it plays an important role in the formation of intermetallic compounds with tetragonal crystal structure, making the compounds have high saturated magnetism. High uniaxial anisotropy and Curie temperature.
