Disc Neodymium Magnet Advantages
1.Material
The super-strong magnets are made of neodymium, iron, and boron (NdFeB). The exact chemical formula is Nd2Fe14B. Neodymium magnets differentiate themselves from ferrite magnets through a much higher remanence induction and coercive force.
2.World's most precise tolerance
The tolerances of magnets can be controlled within ±0.05mm or even more, less samples tolerances can be controlled within ±0.01mm, mass production can be controlled within ±0.02mm.
3.Coating / Plating
NdFeB magnets have some limitations due to their corrosive nature. In wet applications, the use of protective coatings is highly recommended. Coatings that have been used successfully include epoxy coatings, nickel plating, zinc plating and combinations of these coatings.
4.Magnetic Direction: Axial
We can magnetize magnets according to your project needs. The magnetization direction of disc magnets is mainly axial and diametrical magnetization.
