Custom Shape Curved Triangle Irregular Strong Permanent

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.
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.
Other options of coating are zinc, tin, copper, epoxy,silver and gold.
