neodymium magnet description:
At present time, Sintered NdFeB 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 is high residual induction (Br), high intrinsic Coercive force (Hcj) and high Energy Product (BH), and is easily formed into various sizes, shapes. So they have been widely used in commercially available fields since the mid 1980's. makes it suitable for servo motors, disk brushless motors, stepping motors, IT industry, MRI, and audio products. For NdFeB, NdFeB Magents are prone to corrosion in humid environments, It usually need surface treatment according to customer's requirements to protect magnet. The surface treatment method include Zine,Nickel,Tin,Silver,Gold plating,Phosphor and Spray Epoxy Resin etc
