Product Description

Neodymium magnets (NdFeB) are composed of neodymium, iron, boron and a few transition metals. Neodymium magnets retains strong magnetic power for their small size. So an anti-corrosive coating ( electroplating) is used to extend their useful lifespan. The electroplating offer NdFeB magnets with a metallic appearance and found in simple shapes such as, arc and blocks, rings and discs. The NdFeB magnets are fabricated into many shapes and types to fit different applications.  NdFeB are used in motors,alternators,speakers,maglev trains,speakers,cellphones, sensors, closures..

Neodymium magnets (NdFeB) is strongger than SmCo magnets and ferrite magnets. But Neodymium magnets have a lower maximum operating temperature. The grade choosing is a important issue as various grades of neodymium magnets are available with varying temperature and BH max properties. Neodymium 

magnets are 10x stronger than the strongest ceramic magnet

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.
