Introduction
Copper alloys are metal alloys that have the metal copper as their chief component. There are about 400 types of copper alloys. A Unified Numbering System (UNS) has been developed for metals and alloys by the American Society for Testing and Materials (ASTM) and the Society of Automotive Engineers (SAE).
Wrought alloy numbers range from UNS C10000 to UNS C79999. UNS C18135 is a cadmium-chromium copper alloy that has high tensile strength, high conductivity and excellent resistance to softening.
