Depending on the grade NdFeB magnet composition is different, but the main ingredient is inseparable from the original aim of NdFeB Nd (neodymium rare earth metals) Fe (iron) B (boron). NdFeB magnets English name To ndfeb, which contains three major components inside, so if material formulation which greatly changed the material composition, then it is not NdFeB magnets. Generally their proportions are: rare earth neodymium (Nd) 32%: metal elemental iron (Fe) 64%: non-metallic element boron (B) 1% price competition more and more attention in the moment, because of the metal material prices compared high, many manufacturers of NdFeB materials to metal neodymium oxide, neodymium oxide, praseodymium, neodymium, or to reduce production costs. Adding a small amount depending on the material of dysprosium grade selection (Dy), terbium (Tb), cobalt (Co), niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and other elements. For example: the production of high temperature above 80 degrees Celsius NdFeB (H stalls), to be coupled with a little metal dysprosium. In the case of the production of magnetic iron undemanding 加入扎 AUO magnet Shenzhen Co., Ltd.
