Nickel plated copper wire is a wire that is coated with a layer of nickel material on the surface of copper wire through electrolysis, chemical methods, and other methods. Compared to pure copper wire, nickel plated copper wire has significantly improved its corrosion resistance, wear resistance, and hardness, which can better meet the application requirements in subsequent parts and extend the service life of the parts. Before nickel plating the copper wire, in order to make the entire coating more uniform and meet the requirements, it is necessary to perform pre-treatment and wire drawing treatment on the copper wire.

What pre-treatment should be done before nickel plating copper wire

Before nickel plating copper wire, the dirt on the surface of the copper wire should be removed first to maintain its cleanliness and facilitate subsequent nickel plating treatment. Subsequently, the copper wire should be cleaned with hydrochloric acid solution to remove the oxide film on its surface, in order to better clean the impurities on the surface of the copper wire and lay a foundation for subsequent nickel plating treatment.

There are several benefits to wire treatment of nickel plated copper wire, including the following aspects

1. After nickel plating the copper wire, pulling it can make the entire copper wire surface smoother and make the density of the coating more uniform. Generally, the surface color of ordinary nickel plated copper wire is not very uniform, but after wire drawing treatment, it can become smooth and bright in color.

2. Increase the production of nickel plated copper wire and reduce the production cost of enterprises.

3. More conducive to the production of small-diameter nickel plated copper wire. If nickel plating is directly applied to copper wires with relatively small diameters, it is more likely to cause copper wire breakage. After wire drawing treatment, the above problems can be effectively avoided.
