Ndfeb itself is easy to corrosion, oxidation, we generally take the surface treatment to protect the permanent magnet, but can not fundamentally solve the impact of environmental humidity on the magnet.
N52 Largest disc neodymium magnet with countersunk hole
Rare earth magnet is the most powerful permanent magnet nowadays. It is also the most commonly used rare earth magnet. It is
widely used in electronic products, such as hard disks, mobile phones, earphones and battery-powered tools.
In order to avoid corrosion damage, it is necessary to protect the surface of the permanent magnet material, such as electroplating with gold, nickel, zinc and tin, and spraying epoxy resin on the surface.
