Magnetization Direction

The common direction of magnetization is shown in the picture below:

1> Disc, cylinder, and Ring shape magnets can be magnetized Axially or Diametrically. 2> Rectangle magnets can be magnetized through Thickness, Length, or Width. 3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness. The special direction of magnetization can be customized as required.

Grade&Coating

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 the 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.
3>Other options for coating are zinc, tin, copper, epoxy, silver, and gold.
