How to select the coating of Ndfeb strong magnet

How to select the coating of Ndfeb strong magnet

The most commonly used coatings for NdFeb strong magnets are zinc plating and nickel plating, which is what we see gold and silver, although many friends know that magnets need electroplating, but do not know the difference between different coatings. In fact, there are obvious differences between NdFeb and Ni plating in appearance, rust prevention, service life and so on:

Difference of polishing property of NdFeb coating

Nickel plating is superior to galvanizing on polish and gives a brighter appearance. High requirements on the appearance of the product will generally choose nickel plating. Almost all exports are nickel plated. And a few magnets are not exposed, relatively low requirements for the appearance of the product, generally do galvanized can.

Two, ndfeb coating rust difference

After the surface treatment of nickel plating, its corrosion resistance is higher, up to 96H salt spray without rust, and galvanized can only achieve 48H salt spray without rust.

Three, ndfeb coating hardness difference

Nickel plating is also higher than zinc plating, in the process of use, can avoid collision to a great extent, resulting in the ndFeb strong magnet Angle, fragmentation and other phenomena.

Four, Ndfeb coating life difference

Compared with nickel plating, zinc plating has a lower service life than nickel plating due to different surface coatings and different corrosion resistance, mainly reflected in the fact that the surface coating is easy to fall off over a long time, leading to the oxidation of the magnet, which affects the magnetic force.

Five, Ndfeb coating price difference

In this respect, galvanized is extremely advantageous, the price from low to high for galvanized, nickel plating, epoxy resin and so on. The quality of the material and manual difference is also a decisive factor, the conventional galvanized nickel plating for roll plating, nickel plating is through electrolysis or chemical methods on metal or some non-metal plating on a layer of nickel method, so called nickel plating.

The electroplating of NdFeb strong magnet is to add a protective layer on the surface, which plays the role of aesthetics, corrosion and rust prevention, increasing the surface strength and prolonging the service life. You can choose the right coating according to their own needs, choose cost-effective magnet products, the right is excellent!
