Copper/Bright Dip
MIL-C-14550
Copper Plating has primarily been used as an underplate for nickel and chrome plating. It may also be used as a stop off for heat treating as a carburizing and decarburizing shield. Copper is also highly conductive, only second to silver. Seminole Metal Finishing does copper plating as an underplate and a final coating for conductivity followed by a chromate "bright dip" to keep the copper from turning.

| Bright Dip on copper and brass alloys is an acid based chromate conversion coating used to protect and add shelf life to the base material. The parts are first cleaned to remove the oil and dirt that may be on them from processing and manufacturing. After the parts are clean, the parts are process through a chromate conversion coating. The film that forms adds shelf life and prolongs future tarnish and corrosion to the base material. It is not a permanent coating that will stop tarnish forever. However, a sprayed on coat of clear lacquer or polyurathane will further enhance the corrosion resistance of the bright dip. | |
