We all know that the main raw materials for sintered NdFeB permanent magnets are neodymium, iron, and boron. However, many other elements are added to the raw materials, each playing a different role in the magnet. Manufacturers often design product formulations based on user needs, making the raw material formulation a closely guarded secret. The dozen or so elements in sintered NdFeB magnets are like the various seasonings we add to a dish. It is the scientific and systematic combination of these elements with different intrinsic properties and functions that creates the various grades and properties of NdFeB magnets.
