By the rare earth elements R and iron, boron intermetallic compound formed. NdFeB magnets have strong magnetic anisotropy and high saturation magnetization, is now the strongest permanent magnet magnetic, because Nd atoms is flat, the electron cloud is limited to iron atoms do not shiftto form the magnetic constant.
NdFeB is small, light weight and strong magnetic features, is by far the best cost performance magnets.
NdFeB magnets, have the characteristics of :

•  Super strong Br Resident induction. Excellent demagnetization resistance capability.
•  Good Price relative to its high magnetic properties.
•  Coating is needed for NdFeB
•  Surface Treatment Method: Type Information
•  metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel,
•  Organic Epoxy, Nickel+Epoxy coating
•  Temporary Surface: Passivation

A pplication
Due to excellent magnetic properties, Nd-Fe-B type magnet was a wide range of applications, mainly used in electric motors, generators, acoustic transducers, sensors, medical devices and magnetic machinery.
