40*20*5mm N42 NdFeB Permanent Magnets For Automotive Products

 

40*20*5mm N42 NdFeB Magnets , Permanent Magnets For Automotive Products

 

NdFeB magnets (Nd-Fe-B)  are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc. widely due to their perfect characteristic,

 

Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.

★ How to purchase the magnet?

In order to quote you exactly, we need to check the necessary requirements about magnet as below:

1. Magnet Application: such as the speaker, motor, separators, nuclear magnetic resonance and something else.
2. The approximate working temperature,humidity and special request of the magnet’s assembly.
3. The magnet’s property, dimensions, tolerance, surface treatment, and so on.
4. Your standard inspection method for the magnet.
5. Special requirements about the package and transportation.
6. The exact mass production quantity.

 

The specification(dimension) of magnet can be customized according to client's requests and

design
