An aluminum-lithium alloy that provides a balance of properties equivalent to those of Al 7050 with the lower density and high fatigue resistance of lithium-containing alloys is now available. This second generation Li-containing 2XXX alloy has a low lithium content for improved damage tolerance and lower quench sensitivity. Initial results of thermal exposure testing indicate that yield strength is stable and that toughness does not drop very fast, even after significant time at 100 degree C.
