 Product Details 

What grades & shapes are available for neodymium magnets?

Grades N35, N38, N40, N42, N48, N50, and N52 ( M, H, SH, UH, EH, AH series ) are available for all shapes & sizes of NdFeB magnets.

  Magnetization Direction 

Common direction of magnetization showed in picture bellow: 

• Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametricall.
• Rectangle magnets can be magnetized through Thickness, Length or Width.
• Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

Axially Magnetized                    Diametrically Magnetized                    Multi-poles Axially                     Multi-poles Diametrically

 Grade & Coating 

Support all magnet plating , like Ni-Cu-Ni, Zn, Epoxy , Gold,  Silver etc.

• 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.
