    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: New aluminum alloy brazing sheets are disclosed. The new aluminum alloy brazing sheets may include a core, an interliner layer adjacent the core, and a braze liner adjacent the interliner layer. The interliner layer may include a first aluminum alloy having at least 0.35 wt. % Si and from 0.05 to 2.0 wt. % Mg. The braze liner may include a second aluminum alloy having 0.05 to 2.0 wt. % Mg. The first aluminum alloy and the second aluminum alloy may include an amount of magnesium sufficient to achieve Tsolidus(IL)≥5° C. Tliquidus(BL). The new aluminum alloy brazing products may be useful, for instance, in fluxfree brazing.

    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.
