The commonly used coatings for magnets are nickel coating and zinc coating. In addition, a small number of customers choose chrome plating. Today, we mainly talk about the difference between chrome coating and nickel coating for magnets, and which coating is better.
In the actual process, the performance of nickel plating will be more excellent, which is embodied in the bonding force with the substrate. The properties and toughness will not easily produce cracks and peeling.
Chrome plating is not useless. It is better than nickel plating in terms of wear resistance and has a bright surface. It is generally used for decoration, jewelry, cosmetics, etc. Its disadvantage is that the price of chrome plating is higher, the thickness of 12-15um is thinner, and the surface roughness is required. High, and will not be used in many cases.
No need for chrome plating, if brocade plating suffices.
