At present time, Sintered NdFeB Magnet is one
of the strongest magnet materials available. It contributes to the development
of many small and flat motors used in the high-tech industry. It¡¯s high
residual induction (Br), high intrinsic Coercive force (Hcj) and high Energy
Product (BH), makes it suitable for servo motors, disk brushless motors,
stepping motors, IT industry, MRI, and audio products. For NdFeB,its surface is
usually treatd with some special methods.The surface treatment method include
Zine,Nickel,Tin,Silver,Gold plating,Phosphor and Spray Epoxy Resin etc
