Rare Earth Magnet Suppliers Custom Coating Neodymium Magnets 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. Custom Neodymium Magnets AH Magnet carries a large inventory of licensed, permanent, Rare-Earth magnet materials. Magnetic properties for Rare-Earth magnet materials far exceed those of ceramic or alnico materials, making them the preferred magnetic material for many technical applications.
