C16200 (CuCd1) is a cadmium-copper alloy containing 0.8–1.3% cadmium as the primary alloying element, with the remainder being copper . This alloy is renowned for its unique combination of high tensile strength (196–689 MPa) and high electrical conductivity (80–90% IACS), which makes it suitable for applications requiring both mechanical durability and efficient electrical performance . The addition of cadmium enhances resistance to softening, stress relaxation, and fatigue while minimally reducing conductivity . Historically, C16200 was widely used in telephone cords, heating blankets, aerospace wiring, oil exploration signal wires, railway catenary systems, and military applications (e.g., torpedo guide wires) . However, due to cadmium’s toxicity and carcinogenicity, its use has declined, with RoHS-compliant alternatives like C15000 (CuZr) and C18100 (CuCrZr) replacing it .

C16200, a cadmium-copper alloy, is renowned for its unique combination of high tensile strength and electrical conductivity (90% IACS when aged and drawn), properties typically considered mutually exclusive in copper alloys . Its nominal composition comprises 99.0% copper and 1.0% cadmium, with cadmium enhancing strength, heat resistance, and stress relaxation resistance while minimally impacting conductivity .

C22000, commonly referred to as Commercial Bronze, is a copper-zinc alloy with a nominal composition of 90% copper and 10% zinc . Despite its name, it is technically classified as brass due to the zinc content but retains the historical designation "bronze"
