Electric gold plating coating corrosion resistance, good electrical conductivity, easy to welding, high temperature, and has a certain wear resistance (such as doped with a small number of other elements of hard gold), has a good resistance to color, at the same time the gold alloy coating has a variety of colors, gold plating on silver can prevent color.
And the coating ductility is good, easy to polish, so often used as decorative coating, such as plating jewelry, watch parts, art; It is also widely used in the electroplating of precision instruments, printed boards, integrated circuits, vacuum tube shells, electrical contacts and other parts that require long-term stable performance of electrical parameters.
The most used colors are 18K gold, 14K gold, 24K gold.
