Eletroplating

Neodymium magnet are composed mainly of neodymium, iron and boron.if they are not plated, the iron in the material will oxidize very easily, particularly if exposed to moisture. Even normal humidity will rust . Considering the bad corrosion resistance of NdFeb materials ,in order to protect them,it requests to make the different surface treatment .

ΔDisc Magnets Production Flow (Quality Control)  

① Neodymium magnet production processing

Hydrogen explosion+Jet  milling+Sintering+Hypoxia operation process

Sintered NdFeB is the most  widely used rare earth/ permanent magnet material. The metallurgy powder was process  into micro-powder through special Sintering Craft. The production process iludes formula design, cast string, hydrogen explosion,Jet  milling, mixing, molding,Vacuum furnace Sintering , grinding, polishing, surface treatment(coating), packaging . through the( HD+JM+LOP )craft ,the neodymium magnet was feature with  high coercivity and high working temperature.

 ΔHow to order Disc Magnet? 

Our quotation is based on your requests for magnet grade, size, coating, magnetization direction and quantity .

In order to give you our appropriate magnet for your prototype,we still need the other information from you.

①Size

Include Diameter and thickness.  if you can provide your drawings is much better.

②Usage: 

Could you kindly tell us the usage of magnet?

We have N35-N52 ,their have different flux and pull force.

we will recommend the right grade for you according your usage.

③Coating: Does the magnet will attaching the water or exposed in the moist air?

The normal coating is Zn and Ni-Cu-Ni three players coating,

the Ni coating have better anti-corrosion and anti-oxidized performance than Zn.

the black Epoxy coating we also can do ,but ask you high MOQ.

④Magnetization: Axial or Diametrical magnetizing?  

Axially magnetizing is common. 

⑤Quantity:

How many pieces you will need? 

Different requirement correspond to different prices, so we need to check this information with you clearly.
