CuCr1Zr Chromium 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 0.1% zirconium (Zr) and 1.0% chromium (Cr) to copper results in a heat treatable alloy which may be solution treated and subsequently aged to produce these desirable properties. Rod is usually supplied from the mill in the fully aged and drawn condition so no further heat treatment is required by the fabricator.
Typical Uses
Electrical：The main applications are for electrical connectors,switch gear and circuit breakers which require higher mechanical properties.It is also used in generators for commutor bars and end rings for electric motors.
Mechanical/Electrical: Used for welding wheels,spotwelding electrodes.seam welding wheels and tips.Electrode holders and arms; oxygen jet tips. Moulds inserts for non ferrous casting moulds.
