Plating Nickel Block Shaped N40 Neodymium Magnet

Neodymium magnets are extremely strong for their small size,NdFeB magnets are used in motors,alternators,speakers, maglev trains,speakers,cellphones,sensors, closures, magnetic holders,signage... Ndfeb Magnet  is the most commercially produced magnet. Neodymium magnets (NdFeB) retain the highest magnetic power and lowest maxinum operating temperature, so before choosing a grade of Neodymium Magnet this issue should be considered. Various grades of neodymium magnets are available with varying temperature and magnetic properties. 

 Neodymium magnets (NdFeB) are composed of neodymium, iron, boron and a few transition metals.All neodymium magnets oxidize fairly rapidly when exposed, so an anti-corrosive coating is used to extend their useful lifespan.

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.
