Custom Magnet Coatings

As we know, the neodymium iron boron magnets contain 64-66% iron, so it is prone to be corroded and oxidized if coatings are not adopted. Both appearance and magnetic properties of uncoated high performance neodymium magnets would be affected under high temperature, acid condition, alkaline environment, seawater, etc. All in all, coating is necessary to magnets. The common ways include Nickel-Copper-Nickel (Ni-Cu-Ni), Nickel (Ni), Tin (Sn), Zinc (Zn), Gold (Au), epoxy coated magnet, etc.
