Chrome Zirconium Copper Alloy

Chromium zirconium copper alloy are composited by 0.5~1.2% chromium, 0.03~0.3% zirconium and the other is copper. Chromium zirconium copper is often the best choice for applications where a combination of high electrical and thermal conductivity and high strength at higher temperatures is required. The properties of Cu-Cr-Zr are obtained by alloying and through heat treatments combined with cold working. Studies have shown that of all commercially available electrode materials for spot welding mid stee, the lowest electrode costs are obtained with chromium-zirconium copper. The metallurgical behaviour of this alloy is based on transformations at the atomic level. 

Chromium zirconium copper alloy are used widely in areas where high electrical and thermal conductivity are required combined with good mechanical properties. This is a high strength, seam, high conductivity alloy for spot, butt and projection welding which is ideal for plain as well as coated and galvanized sheets.

Uses include Resistance Welding Machine Electrodes, Seam Welding Wheels, Spot Welding Tips, Flash Butt Welding Electrodes, Anvil Contact Bars, Electrical Switch Gear Contacts & Terminals, Electrode Holders, Cable Connectors, Current Carrying Arms and Shafts, Circuit Breaker Parts, Heat Sinks, Short Circuit Rings, MIG welding contact tubes and many other applications where Copper would normally be the ideal choice for High Conductivity but is just not Strong enough.

C18150 Chromium Zirconium Copper is used extensively for cap style resistance welding electrodes. Evidence suggests that it can provide less sticking and resist deformation longer than its chromium copper counterpart in some specific situations.
