Nickel coating on neodymium magnets is a very common coating. Almost seven or eight of ten NdFeB customers choose nickel plating. Today we will talk about nickel plating on neodymium magnets.
The nickel-plated neodymium magnet is divided into single nickel, double nickel, nickel copper nickel, etc. according to the different coating structure;
According to different appearance and color, it is divided into dark nickel, semi-bright nickel and light nickel.
Generally, the nickel-plated layer is mostly bright nickel and semi-bright nickel.
The advantages of nickel plating are that the plating layer is more wear-resistant and environmentally resistant. The worse is that the nickel layer is a ferromagnetic substance. The magnet has a certain influence on the magnetic properties, especially for thin and small products. The improvement method is to use part of the copper layer. Substitute. Electroless nickel and electroplated nickel-phosphorus alloys are weaker in ferromagnetism, but deplating is more troublesome, and they are generally not used as mainstream coatings.
Electroless nickel is relatively more uniform than electroplated nickel and nickel layers, but it is currently not possible to directly plate on the neodymium iron boron substrate, and chemical nickel uses a large amount of complexing and reducing agents, and the plating solution life is short and the impetus for plating is low. , High energy consumption, so it can not be used as mainstream coating.
Nickel-plated products can also be plated with gold, silver, tin, chromium, imitation gold, black nickel and other coatings according to the requirements of the coating.
