Product Detail
Grade from N35~N52 both ok
This thickness can be customer require
Coating can be Ni-Cu-Ni, Zn, Blac
The Neodymium magnet is block shaped, the N52 grade magnets are the strongest magnets available in the world at present, with super strong performance
Permanent Neodymium magnets are the third generation of rare earth magnets, which are composed of Neodymium, Iron, Boron and a few transition metals. They have high remanence, high coercive force, high energy product, and high performance / cost. Currently the permanent Neodymium magnets are the strongest magnets available in the world.
