Disc Neodymium Magnet Advantages



Neodymium magnets have the highest available magnetic energy density, with a (BH)max value of 30 MGOe to 52 MGOe.
This strongest permanent magnet is built from Neodymium Iron Borium - NdFeB.
The use of neodymium magnets in high-tech electronics is very popular because of their high magnetic strength and special performance.

2.World's most precise tolerance

Usually the dimensional tolerance of NdFeB block, round, cylindrical magnet is ±0.05mm, some customers are not strict with the drawings marked ±0.1mm, while for some magnet products that require higher precision we can control to ±0.03mm or even higher.


3.Coating / Plating

Zinc coating provides good adhesion. You will find that the magnets in motors, many of which have a zinc coating, which is used to protect the magnet from corrosion in the surrounding air and to provide mild protection against moisture, water, or salt water. The zinc coating is mainly used for low-temperature applications and where a little protective barrier is required.

4.Magnetic Direction: Axial

The regular magnetic direction of the disc magnet is axially magnetized and diametrically magnetized.
We can magnetize permanent magnets to their saturation level with very powerful magnetization equipment.
