Chromium Copper Official Site of Copper Development ...
Chromium copper alloys are designated as UNS C18050 through C18600, the cast alloys are C81400 through C81540. The age hardening reaction occurs because the solid solubility of chromium in copper decreases as the temperature decreases. The structure of slow cooled chromium copper is a two phase mixture of chromium and alpha copper.
