CDA/UNS
C18200 Chromium Copper is a general purpose resistance welding electrode material recommended for spot and seam welding of most materials. It is suitable for spot welding electrodes, projection welding electrodes, seam welding wheels, shafts and bearings, flash welding electrodes, and current-carrying structural members. It is also available as high strength and high electrical conductivity castings for use as welding platens and secondary circuit structural members. This material derives its properties from a combination of chemistry, heat treatment, and cold work. Class 2 material should be used in the heat-treated condition.
