Copper Plating Process
Copper plating provides good corrosion resistance when used as an undercoat for other plated coatings. Copper finishes range from matte to very shiny, and there are several copper plating processes available. Each process is designed for a specific purpose, ranging from decorative to heat treat stop-off.
Cyanide based bath chemistry produces a matte finish, which is favored for its diffusion blocking character. It is also essential for plating on aluminum, steel and zinc, as it adheres well and minimizes immersion deposits. Cyanide copper has excellent throwing power, which leads to less thickness variations.
AFT has extensive experience in plating threaded stainless steel parts for the petroleum industry to reduce galling of stainless valves and parts.
