Neodymium magnets (Nd2-Fe14-B) are composed of neodymium, iron, boron and transition metals. Neodymium Magnet is the most strong magnetic material with strong magnetism which are suscepting to demagnetization at elevated temperatures. Neodymium magnets have corrosive phenomenon in huimid situations, thus neodymium magnets are always been treated with anti corrosion coatings to prevent the rust, the coating that usually have been plating on magnets are epoxy coating, nickel plating,zinc coatings nicuni coatings and more. 
Main Manufacturing process of ndfeb magnets
1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.
2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.
3.Wire cutting: ndfeb magnets are fragile materials operated in wire cut machines for the
tailored irregular shapes.
4.Grinding process: Grinding process: To reach the tolerance of magnets.
5.Plating: Neodymium magnets had been treated with different platings to prevent rust.
The popular platings for neodymium magnets are epoxy, nickel, NICUNI ,zinc and even
silver plating and gold plating.
6.Magnetization: the procedure are processed with magnetization machine with magnetic
feild ranged from 2~100 koe.
