Epoxy Coated Arc Magnets

The most common coatings for curved (arc) neodymium (NdFeB) magnets is epoxy. Epoxy coating has the advantages of high-temperature resistance and salt spray resistance. Our epoxy-coated neodymium arc magnets are primed with nickel-copper coating, they have a three-layer coating of Ni-Cu+Epoxy.

Our epoxy-coated arc neodymium magnets (magnetic tiles) are used in compressors, elevators, and motor fields.
