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.

Neodymium Iron Boron Magnet
About this Item
There are more than 10 coating methods and coating is high temperature resistant, solvent resistant, and multi-colored.
The common ways include Nickel-Copper-Nickel (Ni-Cu-Ni), Nickel (Ni), Tin (Sn), Zinc (Zn), Gold (Au), Expoxy, etc.
Otherwise, magnets with high temperature resistance can be coated with rubber and silicon.
Application
Speaker magnet, sensor magnet, tractor magnet, wind generator magnet, magnetic separator magnet, arc magnet, etc.
