Zinc die-cast parts are Copper-Nickel-Chrome Electroplated. One of the workhorse finishes for outdoor corrosive applications for many years, it begins with a thin layer copper to protect the zinc against the acidity of subsequent baths. This is followed with one or more layers of nickel, which provides a continuous corrosion resistant barrier. Finally, a layer of chromium is applied to give the desired shiny, silvery appearance and to protect the nickel against mechanical forces such as wear and erosion.
Eastern Plating offers this finish in both a Satin or Shiny finish. We are currently plating Zamac 3, 5 and 8 for both the Automotive and Furniture Industry.
