More Information
Summary:A family of aluminum base alloys exhibiting superior ambient- and elevated-temperature strength, superior ductility at ambient and elevated temperatures, extrudability, forgeability, weldability, and an unexpected natural aging response, and consisting of from about 2.0 to about 9.8 weight percent of an alloying element selected from the group consisting of copper, magnesium and mixtures thereof, said magnesium comprising at least 0.01 weight percent, from about 0.01 to about 2.0 weight percent silver, from about 0.05 to about 4.1 weight percent lithium, less than about 1.0 weight percent of a grain refining additive selected from zirconium, chromium, manganese, titanium, boron, hafnium, vanadium, titanium diboride, and mixtures thereof, the balance substantially all aluminum.
