Cube Magnet Coatings

We offer nickel (Ni-Cu-Ni), black nickel (Ni-Cu-Ni-BlackNi), gold (Ni-Cu-Ni + Au), rubber and plastic coatings for our cube magnets. Our standard coating is a 3-layer nickel-copper-nickel (Ni-Cu-Ni) coating that helps protect against moisture and corrosion, enhances durability and provides a smooth silver finish. Additional coatings such as epoxy (Ni-Cu-Ni + epoxy) and silver (Ni-Cu-Ni + Ag) are available. See custom neodymium cube magnets for more details.

Cube Magnet Magnetization Direction

Our cube magnets are magnetized through their thickness. Since all three dimensions of a cube are equal, the magnetization direction could technically be described as through the length, width or thickness. We label cube magnets as through-thickness magnetized for consistency.
