CuZr – UNS.C15000 Zirconium Copper Alloys
C15000 Details & Applications:
C15000 Zirconium Copper
CuZr – UNS.C15000 Zirconium Copper is an excellent and unique copper alloy with high electrical conductivity, hardness, and ductility, moderate strength, and excellent resistance to softening at elevated temperatures. The addition of 0.15% zirconium (Zr) to copper results in a heat treatable copper alloy which may be solution treated and subsequently aged to produce these desirable properties. Rod is supplied from the mill in the fully aged and drawn condition so no further heat treatment is required by the fabricator. The softening temperature of properly heat treated C15000 rod exceeds 500°C as compared to unalloyed, pure copper which softens at 200°C and silver bearing coppers which soften at 350°C.
Typical Application for C15000 Zirconium Copper Alloys:
Electrical Industry: Resistance Welding Electrodes, Circuit Breaker Switches, Stud Bases for Power Transmitters, Rectifiers, Diodes, Switches, Commutators
Consumer: Rod Extensions, Pencil-type, Light Soldering Guns, Tips
Industrial: Connectors, Solderless Wrapped, Welding Wheels, Resistance Welding Tips
