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: Brazing sheets, articles formed from brazing sheets, and methods of forming articles are provided. In certain embodiments, a brazing sheet comprises a core comprising an aluminum alloy and a brazing layer comprising a 4XXX series aluminum alloy. The brazing layer is disposed on the core. The core acts as a sacrificial anode and the brazing layer acts as a cathode of a first galvanic circuit within the brazing sheet.

Abstract: Brazing sheets, articles formed from or including all or a portion of a brazing sheet, and methods of forming articles of manufacture are provided. A brazing sheet embodiment comprises a core layer, a brazing layer, and an interliner layer intermediate the core layer and the brazing layer. The core layer comprises a 6XXX series aluminum alloy having a core layer solidus temperature of at least 600° C. and comprising at least 0.3 weight percent magnesium based on a total weight of the 6XXX series aluminum alloy. The brazing layer comprises a 4XXX series aluminum alloy having a brazing layer solidus temperature lower than the core layer solidus temperature. The interliner layer comprises a first aluminum alloy comprising no greater than 0.5 weight percent manganese based on a total weight of the first aluminum alloy.

Abstract: Brazing sheets, articles formed from or including all or a portion of brazing sheets, and methods of forming articles are provided. A brazing sheet comprising a core layer, a brazing layer, and an interliner layer intermediate the core layer and the brazing layer. The core layer comprises a first aluminum alloy having a first recrystallization temperature. The interliner layer comprises a 3XXX series aluminum alloy having a second recrystallization temperature greater than the first recrystallization temperature. The 3XXX series aluminum alloy comprises, in weight percentages based on total weight of the 3XXX series aluminum alloy: 0.01 to 0.2 silicon; 0 to 0.6 copper; 0.8 to 1.9 manganese; 0 to 0.2 chromium; 0 to 0.15 zirconium; 0 to 0.4 iron; 0 to 3 zinc; 0 to 0.2 magnesium; 0 to 0.3 titanium; 0 to 0.1 vanadium; 0 to 0.5 bismuth; aluminum; and impurities.
