What is Gold?
Gold is a very ductile malleable precious metal. It is a heavy, yellow, metallic chemical element. Gold is used in the manufacture of a wide variety of products including jewelery, electronics, and gift ware to name a few. Gold finish appearance is pale yellow to orange yellow; there are many colours and tints commercially available.
Gold has excellent corrosion resistance. The higher the carat gold and layer thickness, the greater the long term resistance to oxidation and discoloring. Gold finishes can be made harder by adding an alloy to the formula; however, in some cases this could limit the maximum layer thickness that could be plated due to embitterment of the plated layer.
