Recently, some customers have mentioned what the surface treatment of our NdFeB magnets generally need to be electroplated? We come to talk with everyone about the electroplating of magnets.
1. What is the surface treatment method of NdFeB magnet?
The commonly used electroplating of NdFeB includes the following three types: "zinc plating, nickel plating + copper + nickel, nickel plating + copper + chemical nickel. Others also include gold plating, silver plating, tin plating, black nickel plating, black epoxy, etc. .
2. What is the best coating on the surface of the magnet?
In fact, this question is difficult to answer. Consider your practical use. Which is better? The best for you.
If there is no special requirement for the magnet, it can be galvanized. If the magnet has salt spray resistance requirements, such as 48 hours, nickel plating can be selected.
3. What is the color of each coating of the magnet?
NdFeB magnet surface treatment
4. What is more resistant to salt spray and corrosion?
The following table shows the evaluation of salt spray resistance, temperature resistance and magnet corrosion
Coating performance
5. Can NdFeB be electroplated?
Of course it is possible, but it is usually recommended to carry out electroplating treatment to make the service life of the magnet longer. Usually, the case of non-electroplating is very common in the sample stage, because the non-electroplating can make the sample faster and does not affect the performance. It can be electroplated together when waiting for bulk goods.
