Magnet FAQ

What is the difference between nickel plating and zinc plating with neodymium magnet?

Many people ask about the difference between galvanizing and nickel plating on magnets. What are the differences in appearance, price and rust resistance between galvanizing and nickel plating on magnets?Next, the strong magnet manufacturer courage gives you a detailed description of galvanized and nickel-plated appearance pictures.
The surface plating methods of magnets are different, which is always difficult. The following is the analysis provided by professional manufacturer Courage.
Zinc plating: refers to the surface of metals, alloys or other materials coated with a layer of zinc, with a silver appearance, in the acid-base fixed various living substances and natural environment can ensure that products avoid deformation.

1. Price
Zinc has the advantages of galvanizing, nickel plating and chromium plating from low to high prices. Material and manual differences determine prices. Conventional galvanizing and nickel plating are barrel plating and chromium plating are hanging plating. Nickel plating: Electrolytic or chemical plating of nickel on metals or some non-metals is called nickel plating.

2. Polishability
Because nickel is superior to zinc in polishing, it is brighter in appearance.

3. Hardness of Magnets
It is also higher. In general use, collision can be avoided to a great extent, which makes the magnet angle drop.

4. Performance
After the treatment of nickel surface, the temperature resistance has been improved a lot, and the conductive properties of nickel itself have been added.

5. Antirust Ability
Zinc plating is general, nickel plating is good, chromium plating is best.

The way of electroplating is mainly determined by the environment in which the magnet is used. Nickel plating is recommended if the magnet is used in a high environment. The price of nickel is higher than that of zinc, and zinc is superior to nickel in price.
