Description
ERCu is a copper based welding alloy used for GTAW and GMAW Welding. It can equivalent to: Oxford Alloy Deox.
Applications
Developed to provide dense, high quality deposits with relatively high electrical conductivity for use in joining and overlay with the inert-gas processes.
Primarily used to fabricate deoxidized copper and to weld repair copper castings. It may also be used to weld galvanized steel and deoxidized copper to mild steel where high strength joints are not required.
