When cadmium is added to copper, the material becomes more resistant to softening at elevated temperatures. The more cadmium that is added, the more heat resistant the material becomes. Cadmium copper is used in applications such as trolley wire, heating pads, electric blanket elements, spring contacts, connectors, and high strength transmission lines. It is also used for soldering applications, particularly to join components in automobile and truck radiators and semi-conductor packaging operations.
SAE J461
C16200 Cadmium Copper alloy offers a unique combination of high tensile strength and high electrical conductivity for an industry where these properties are generally considered incompatible. The nominal composition of 99.0% copper and 1.0% cadmium can lead to these unique properties.
Typical Application for C16200 Cadmium Copper alloys:
Electrical Industry: Resistance Welding Electrodes, Circuit Breaker Switches, Stud Bases for Power Transmitters, Electrical Conductor Material
Consumer: Rod Extensions, Pencil-type, Light Soldering Guns, Tips
Industrial: Connectors, Solderless Wrapped, Welding Wheels, Trolley Wires
C16500 Cadmium Tin Copper
Typical Uses for C16500:
Electrical: Springs, Contacts, Flat Cable, Trolley Wire, Clips
Industrial: Resistance Welding Electrodes
Density: 0.321 lb/in3 at 68 F
