As the third generation of rare earth permanent magnets, NdFeB magnet is by far the best performance nowadays.

Rare earth sintered NdFeB ring magnet:

NdFeB (Neodymium Iron Boron) magnet is an alloy magnet made from ND, Fe, B and other metal elements. As the third generation of rare earth permanent magnets, it is by far the best performance in contemporary.

Specification:
1. High performance, cost ratio
2. High intrinsic coercive force after concocting
3. It can stand high working temperature, up to 200 Celsius degree.
4. It is prone to corrosion in humid environments, need surface treatment: Zinc, Nickel, Silver, Gold-plating, Phosphor, rubber and Spray Epoxy Resin.
5. Quick delivery and good service
6. It is easily formed into various sizes

Production process:
Raw Materials-->Mixture--->Vacuum Melting--- > Powder Production--- >Molding ---> Vacuum Sintering--- > Testing--- >Mechanical Processing--- > Surface Coating--- >Magnetized--- > Inspecting--- > Packing and Shipping.

Application:
Electronics (sensors, microphone assemblies), aviation, motors (vibration motors, DC motors, servo motors and linear motors), automobiles, MRI/NMR, medical apparatus and transmission machine and even in many details of our everyday life.
