AC 5123 Cu is a blackening process that creates a jet black oxide layer resistant to temperatures of 185 0C on copper alloys containing 65% or more copper.
The black coating provides a good base for organic finishes such as lacquer and enamel. The coating is normally resistant to internal atmospheric conditions and additional protection can be achieved by oiling, waxing or lacquering. The coating is not resistant to open atmospheric conditions without any additional application.
