Hard Copper Alloys

Product Description

CuCr1Zr – *********0 Chromium Zirconium Copper C****0 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. The softening temperature of properly heat treated C****0 rod exceeds **0°C as compared to unalloyed pure copper which softens at **0°C, and silver bearing coppers which soften at **0°C. Furthermore, many evidences shows that C****0 can provide less sticking and resisting deformation longer than its C****0 counterpart in some specific situatons. Typical Application for C****0 Chromium Zirconium Copper Alloys: Electrical Industry: Resistance Welding Electrodes, Circuit Breaker Switches Consumer: Rod Extensions, Pencil-type, Light Soldering Guns, Tips Industrial: Welding Wheels, Tips and Rod extensions for resistance seam and spot welding Available Sizes: Custom Diameter & Sizes, Random Mill lengths Available Products (forms): Round bars, Flat bars, Square bars, Rectangular bars, Hexagon bars, Plates Custom shapes are available upon request.
