The first thought that may come to mind concerning gold is for jewelry. However, gold can be used for plating purposes for all types of electrical equipment. There are times when the cost of gold can limit its applications but for the most part, gold plating, when used for decorative purposes, can be less expensive than you would think. Deposits of gold can be changed so as to provide different characteristics of solderability, hardness, color, wear and luster. It will also not tarnish or oxidize.
