The corrosion resistance of Neodymium magnets is considered poor. Surface coating or plating is therefore highly recommended for Neodymium magnets. All kinds of surface coating are available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn, Chrome. We also applied special surface protection to Neodymium magnets, like ABS coating, Rubber coating, Parylene coating etc.
