    Abstract: Heat treatable aluminum alloy strips and methods for making the same are disclosed. The heat treatable aluminum alloy strips are continuously cast and quenched, with optional rolling occurring before and/or after quenching. After quenching, the heat treatable aluminum alloy strip is neither annealed nor solution heat treated.

    Abstract: The present application discloses wrought 2xxx Al—Li alloy products that are work insensitive. The wrought aluminum alloy products generally include from about 2.75 wt. % to about 5.0 wt. % Cu, from about 0.2 wt. % to about 0.8 wt. % Mg, where the ratio of copper-to-magnesium ratio (Cu/Mg) in the aluminum alloy is in the range of from about 6.1 to about 17, from about 0.1 wt. % to 1.10 wt. % Li, from about 0.3 wt. % to about 2.0 wt. % Ag, from 0.50 wt. % to about 1.5 wt. % Zn, up to about 1.0 wt. % Mn, the balance being aluminum, optional incidental elements, and impurities. The wrought aluminum alloy products may realize a low strength differential and in a short aging time due to their work insensitive nature.

    Abstract: High strength forged aluminum alloys and methods for producing the same are disclosed. The forged aluminum alloy products may have grains having a high aspect ratio in at least two planes, generally the L-ST and the LT-ST planes. The forged aluminum alloy products may also have a high amount of texture. The forged products may realize increased strength relative to conventionally prepared forged products of comparable product form, composition and temper.
