Copper Nickel Chrome and Nickel Nickel Chrome Plating Differences and Applications
Author:Robby
First, the difference between copper-nickel-chromium plating and nickel-nickel-chromium plating
Copper-nickel-chromium plating is a plating method that forms a thin protective layer by means of copper, nickel and chromium plating. While nickel-nickel-chromium plating is a plating method that achieves protection only through nickel and chromium plating.
Specifically, the biggest difference between copper-nickel-chromium plating is that before nickel plating, a layer of copper is coated on the substrate, which better protects the surface of the substrate, while nickel-nickel-chromium plating directly coats the substrate with a layer of nickel, and then proceeds to chromium plating.
In addition, the composition of the two plating methods is slightly different. The main components of copper-nickel-chromium plating are copper, nickel and chromium, while nickel-nickel-chromium plating is mainly composed of nickel and chromium.
Second, the application of copper-nickel-chromium plating and nickel-nickel-chromium plating
1. Application of copper-nickel-chromium plating
Copper-nickel-chromium plating can achieve efficient corrosion protection in a low-oxygen environment, so it is widely used in the manufacture and repair of automobiles and other vehicles. In addition, it can be used as a surface treatment method for manufacturing watches, jewellery, taps and other decorative items.
2. Application of nickel-nickel-chromium plating
The main application of NiNiCr plating is in the automotive industry, where it can be used to add value to the appearance of vehicles because of its high surface finish and excellent corrosion resistance. At the same time, nickel-nickel-chromium plating can also be applied in electrical appliances, machinery and other industries.
Third, the advantages and disadvantages of copper-nickel-chromium plating and nickel-nickel-chromium plating
1. Advantages and disadvantages of copper-nickel-chromium plating
Copper nickel chromium plating has good toughness, long life, high temperature resistance and corrosion resistance, and can well inhibit bacterial growth, but the production process is relatively more complex and costly.
2. Advantages and disadvantages of nickel-nickel-chromium plating
Nickel-nickel-chromium plating has high surface finish, good corrosion resistance, long service life, and relatively low production process and cost. But it is easy to rust under high temperature and humid environment.
Conclusion
Overall, CuNiCr plating and NiNiCr plating can achieve efficient corrosion protection in different application scenarios. The choice of which plating method needs to be weighed according to the specific application requirements.
