Neodymium Disc Magnets (Round type)

Rare Earth Disc Magnets, also called neodymium disc magnets, are the perfect marriage of small size and maximum power or strength.

The neodymium disc magnets are the disc magnets made from neodymium magnetic material, it also called disc neodymium magnets, the disc is the most common shape for neodymium magnets, disc neodymium magnet looks round and flat which expressed by diameter and thickness. Mostly magnetized through thickness, that is axially magnetized.

With a diameter greater than the thickness, our neodymium disc magnets provide a very strong magnetic field and high coercivity. Excellent value for money ensures that Neodymium discs are among the most widely used commercially available magnets.

Engineering drawing is important and necessary for disc shaped magnets. To avoid any misunderstanding of the dimensions and positions, please provide a clear drawing with detailed specifications, tolerance and additional requirements if any.

We list some drawings of common types of neodymium magnet disc as follows for your information.

Surface treatmen

For iron component (about 66%), it is easy disadvantages oxidizing power is strong rust there often (neodymium magnet) Nd-Fe-B sintered magnet. Surface treatment that a mandatory essential to prevent it, there is a method using various materials in it. To determine the material of plating depending on the environment used is neodymium.
