ABSTRACT:
A family of alloys based upon aluminum-copper-magnesium-silver alloys to which lithium has been added, within specified ranges, exhibits superior ambient- and elevated-temperature strength, superior ductility at ambient and elevated temperatures, extrudability, forgeability, weldability, and an unexpected natural aging response.
