Custom N35-N54 Grade Circle Neodymium Magnets Sintered Ndfeb Magnets
Over time, neodymium magnets will corrode after exposure to oxygen and moisture. Fortunately, there is a coating available for neodymium magnets. The coating is a protective barrier that prevents oxygen and moisture from reaching the neodymium material of the magnet. All shapes of magnets are coated with a nickel layer to prevent rusting.

Support all magnet plating , like Ni-Cu-Ni, Zn, Epoxy , Gold,
Silver etc.
1. Neodymium magnets are made of Neodymium, Iron and Boron.
If left to the elements, the iron in magnet will rust.
To protect the magnet from corrosion and to strengthen the brittle
magnet material, it is usually preferable for the magnet to be
coated.
2. There are a variety of options for coatings, but nickel is
the most common and usually preferred. Our nickel plated magnets
are actually triple plated with layers of nickel, copper, and
nickel again. This triple coating makes magnets much more durable
than the more common single nickel plated magnets.
