Product Description

Neodymium Magnet in arc Shape, usually be applied in DC motors and AC motors and will offer the strong magnetic powers.38SH,40SH,42SH,44SH,45SH are common grades for small size DC motors and wind power generatings.etc. Neodymium magnets consist of neodymium,iron and boron. Neodymium magnet is a kind of rare earth magnet with prodigious magnetic power. 

The Sintered neodymium magnet and bonded neodymium magnet are the two members of neodymium permanent magnet family. The Sintered neodymium magnets have the strongger magnetism than bonded neodymium magnets, while bonded magnets is weaker in magnetism but available for the produce of complex irregular shapes . If the high working temperature is required,the higher grade of neodymium magnet will be needed.

Main Manufacturing process of ndfeb magnets 

1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.

2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.

3.Wire cutting: ndfeb magnets are fragile materials operated in wire cut machines for the

tailored irregular shapes.

4.Grinding process: Grinding process: To reach the tolerance of magnets.

5.Plating: Neodymium magnets had been treated with different platings to prevent rust. 

The popular platings for neodymium magnets are epoxy, nickel, NICUNI ,zinc and even 

silver plating and gold plating.

6.Magnetization: the procedure are processed with magnetization machine with magnetic 

feild ranged from 2~100 koe.
