Surface Coating

Neodymium magnets have poor resistance to corrosion. In order to protect the neodymium magnet from corrosion, usually, neodymium magnet will be plated.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking. Meanwhile, other options for coating are Color Zinc, Zinc, Epoxy resin, Silver, Gold, Tin, and so on.
