Disc Neodymium Magnets(30*5mm)
Neodymium (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.
