Abstract: New methods of making cold formed, extruded aluminum lithium alloys, and unrecrystallized products made therefrom are disclosed. A method may include one or more of heating an unrecrystallized extruded aluminum-lithium product to a treatment temperature, cooling the unrecrystallized extruded aluminum-lithium product from the treatment temperature to a post-treatment temperature, and cold forming the unrecrystallized extruded aluminum-lithium product into a second product form. Due to the unique processing conditions of the method, the second product form may wholly or partially retain the unrecrystallized microstructure.

Abstract: New aluminum alloys having an improved combination of properties are disclosed. In one approach, anew aluminum alloys may include from 0.50 to 3.0 wt. % of X, wherein X comprises (wt. % Bi+wt. % Sn), from 0.50 to 4.0 wt. % Si, from 0.30 to 2.5 wt. % Mg, up to 1.5 wt. % Cu, up to 2.0 wt. % Zn, from 0.05 to 1.5 wt. % Mn, up to 0.70 wt. % Fe, up to 0.35 wt. % of Cr, up to 0.25 wt. % each of Zr and V, and up to 0.15 wt. % Ti, the balance being aluminum, incidental elements and impurities. The new aluminum alloys may comprise at least 0.20 wt. % excess silicon.
