Description and Application
COPR-TRODE® is a deoxidized copper alloy developed to provide dense, high quality deposits with relatively high electrical conductivity for use in joining and overlay with the inert-gas processes.
COPR-TRODE® spooled wire and filler metal rod are used primarily to fabricate deoxidized copper and repair weld copper castings with the gas metal-arc and gas tungsten-arc processes. It may also be used to weld galvanized steel and deoxidized copper to mild steel where high strength joints are not required.
COPR-TRODE® spooled wire and filler metal rod are used to overlay surfaces to resist corrosion.
