Copper plating is one of the most common metal finishes. It provides a soft, reddish, pliable surface with excellent electrical conductivity. It is most commonly used as an undercoat and can be easily buffed to a high sheen. Usually, copper is not used as a final finish due to its low resistance to tarnishing. As an undercoat, the process often includes two steps, a very thin copper strike (less than 0.0001 inches of thickness) providing excellent coverage followed by a second copper plating solution designed to give greater thickness.
