Uns.C18150/c181 Zirconium Copper

Cucr1zr uns. C18150 chromium zirconium copper c18150 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 c18150 rod exceeds 500c as compared to unalloyed pure copper which softens at 200c, and silver bearing coppers which soften at 350c. Furthermore, many evidences show that c18150 can provide less sticking and resisting deformation longer than its c18200 counterpart in some specific situations. Typical application for c18150 chromium zirconium copper alloys: Electrical industry: resistance welding electrode, 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 Plywood cases, wooden cases, plastic pipe
