Details of the NdFeB

NdFeB has the best performance among the rare-earth permanent magnets. It is the allloy magnet of Neodymium(Nd), Iron(Fe), Boron(B) and some other microelements, produced through the Powder Metallurgy technology. NdFeB is called the “king of magnet”due to its strong power(high residual induction, coercive force and energy product), competitive price and great machinability.

NdFeB is easy to be oxidated andcorroded, so it usually requires surface treatment. It can be plated Phosphate, Au, Ag, Zn, NiCuNi, Epoxy and so on in our factory. All coatings meet the requirements of RoHS.

NdFeB, as the third generation of rare earth magnet, China owns abundant rare earth resources and supplies the world 70-80%rare earth magnet. Facing the fierce competition, er aim at the fields of high-end motors, speakers, medical apparatus, etc. Through our continuous exploration and research. The performance of our products have reached the first-class level of the world.
