ABSTRACT:
Welding alloys based upon aluminum, copper, mangesium, silver and lithium have been found to possess exceptional properties such as resistance to hot cracking, high strength and ductility, and an unexpected natural aging response. The aluminum-base alloys may contain 3.5 to 7 weight percent Cu, 0.05 to 1.5 weight percent Mg, 0.01 to 2 weight percent Ag, 0.1 to 4 weight percent Li, and 0.01 to 2 weight percent grain refiner.
