Copper-Nickel-Chrome

Commonly referred to as Chrome Plating.

The Copper-Nickel-Chrome process is a plating technique used to coat metal parts with protective layers of copper, nickel, and chrome. This process has sometimes been called “triple chrome”, or “show chrome” due to the lustrous, highly reflective finish results. 

Here are the 4 essential steps in the chrome plating process:

1. Surface Preparation: The metal part’s surface is meticulously cleaned using methods like sandblasting, chemical cleaning, or ultrasonic cleaning.
   
   
2. Copper Plating: A layer of copper is applied to the cleaned surface. This can be done through either an electrolytic or electroless process. Copper provides corrosion protection and helps level the surface. Next, the copper layer is highly polished to a near mirror finish.
   
   
3. Nickel Plating: Next, a thin layer of nickel is added over the copper. Nickel enhances durability and corrosion resistance. Nickel also provides that reflective silver finish under the chrome layer.
   
   
4. Chrome Plating: Finally, a layer of chrome is applied over the nickel. This gives the part a bright, shiny finish that resists tarnishing. The protective chrome layer is exceptionally hard and durable, compared to the underlying metals.

Benefits:

• Exceptional Corrosion Protection: The process shields metal parts from rust and wear.
• Aesthetics: It provides a glossy, metallic finish.
• Durability: Better protection than single-metal coatings like zinc or chromium plating.
• Time and Cost Savings: No need for additional painting after coating.
