Product Description

Neodymium ( NdFeB ) magnets are a combination of Neodymium (Nd), Iron (Fe), and Boron (B).
They are the strongest type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes, and grades. The round/disc neodymium magnets can be used for industry, retail, office, DIY, etc.

Disc Neodymium Magnet Advantages

1.Material:
Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal system formed by Neodymium, iron and boron (Nd2Fe14B).

2.World's most precise tolerance
The tolerances of products can be controlled within ±0.05mm or even more, small batch sample tolerances can be controlled within ±0.01mm, mass production can be controlled within ±0.02mm.

3.Coating / Plating
Neodymium magnet is mainly composed with Nd-Pr, if the magnet is not electroplated, it will rusted and corroded easily when the magnet is under moist air environment.
Regular coating: Nickel (NiCuNi), Zinc, Black Epoxy, Rubber, Gold, Silver, etc.

4.Magnetic Direction: Axial
The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
The regular magnetic direction of disc magnet are axially magnetized and diametrically magnetized.
