Product Description

Neodymium magnet is the most widely used rare earth magnet. It is the alloy of neodymium,iron and boron which have the most stronggest magnetism and have replaced other permanent magnet in many industrial areas.

The ndfeb structure is very vulnerable with oxygen and humid, the iron element will separate from Nd2Fe14B structure and arrayed randomly, which will weaking the magnetic field  and decline the magnetic power. Protective coatings like Nickel,Zinc,NiCuNi, Epoxy, Gold, color glaze have applied to the surface.

Application

Neodymium magnet have a widely application area on modern electric and electronic product,computer,earphone,motor,alternator, sensor, MRI... By using the neodymium magnet , product size will smaller and function will better. Neodymium magnet also be called as ndfeb magnet,they could catch iron steel, hence neodymium magnet could be designed as a magnetic catcher for catching things with ferromagnetic surface.

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.
