Neodymium magnets can be manufactured by sintering, compression bonding.
The Neodymium magnet is easy corrosive, so its surface is usually treated with some special methods. Nickel is the most common and usually preferred to protect the magnet from corrosion. Our Nickel plated magnets are actually tripled plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are Zinc, Tin, Silver, Gold plating, Phosphor and Spray Epoxy Resin . Epoxy Plated Neodymium Stepped Magnets in Podium Shape
Large diameter anisotropic sintered neodymium iron boron radiation ring for Motors, hub motor、generators, navigation, magnetic drives, magnetic fluid bearings, medical, magnetic suspension，maglev,magnetic gearboxes, supercapacitors, etc。
Neodymium magnets area member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
