Product Description
Disc neodymium magnets, also known as round magnets, are among the most popular types of magnets for retail. They are extremely versatile in their use and achieve remarkable adhesive forces even at a small size. Responsible for that is the neodymium iron boron combination, which is currently the strongest available magnet material in the world.

Disc Neodymium Magnet Advantages
1. Material
Neodymium magnets have outstanding magnetic properties (force and endurance) and are far better than Ferrite and AlNiCo magnets. The products’ cpk value of Br and Hcj is much higher than 1.67 with excellent consistency. The surface magnetism and magnetic flux consistency in the same batch of products can be controlled within +/-1%.
2. World's most precise tolerance
The tolerances of products can be controlled within ±0.05mm or even more.
3. Coating / Plating
Neodymium magnets are a composition of mostly N d, Fe, and B. If left exposed 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. There are a variety of options for coatings, but Ni-Cu-Ni is the most common and usually preferred.
Other options of coating: Zinc, Black Epoxy, Rubber, Gold, Silver, etc.
4. Magnetic Direction: Axial
The regular magnetic direction of the disc magnet is axially magnetized and diametrically magnetized.
If the magnetization direction of the round magnet is axial, the maximum pull force is on the top and bottom of the magnet.
If the magnetization direction of the round magnet is diametrical, the maximum pull force is on the curved surface on both sides of the magnet.
