Copper Chromium Zirconium
The C18150 Copper Chromium Zirconium is the copper alloy that is less sticky and resist deformation in comparison to other copper chromium alloys. The alloy is mainly used in cap style resistance welding electrodes and is highly recommended for cold as well as hot rolled spot and seam welding.
Applications:
- Consumer Applications : Pencil-type & Light Soldering Guns: Tips, Rod Extensions
- Electrical Applications : Resistance Welding Electrodes
- Industrial Applications : Welding Electrodes, Welding Wheels, Tips and Rod Extensions
