Zinc Cr3+ coated Rare Earth Neodymium magnets has a good shield to against salt spray. Zinc Cr3 The color of zinc coating is color blue. Neodymium Iron Boron Magnet has poor resistance to corrosion, in order to prevent ndfeb magnet from corrosion, surface coating is needed. There is a variety of surface plating available, such as, Nickle plating, Nickel-Copper-Nickle plating, Epoxy resin plating, Zinc plating, gold coating, rubber coating and more.
