Nickel is a kind of material with relatively stable performance, and it is plated on the surface of copper wire or steel and other metals as a coating, which can better improve the performance of the original metal, improve its durability and the scope of application. Such as nickel-plated copper wire, it is a kind of material that is used more in people's lives and industrial production

Compared with pure copper materials, nickel-plated copper wire has the following improvements in performance：

1, reduce the possibility of copper wire being oxidized in the air. The nickel-plated layer of nickel-plated copper wire has excellent performance stability and can form a passivation film in a very short time to better cope with the corrosion caused by air, alkaline or acidic substances. And the crystal is very fine, the polishing performance is good, even if it is exposed to the air for a long time, it can maintain a good luster, and can be used as a decoration.

2, the hardness of copper itself is relatively small, easy to deformation. The hardness of the nickel-plated layer is very high, and the nickel-plated copper wire formed after nickel plating on the surface of the copper wire has a high hardness, and the wear resistance is effectively improved in the subsequent use. It is often used in some cable production or internal connection of electronic products.

It should be noted that the copper itself is malleable and highly permeable, and the internal copper color of the nickel-plated copper wire made by it may permeate out after a period of use, and the product discoloration may occur. Therefore, when we nickel plating copper wire, we must pay attention to controlling the thickness of the coating, and pay attention to achieving uniform thickness of the entire coating, so that the material can be applied to better meet the needs of everyone
