    Abstract: A framed assembly includes a first frame member defining a first inner channel, a second frame member defining a second inner channel and positioned adjacent the first frame member at a corner joint, and a corner cleat having a first leg received within the first inner channel and terminating at a first end of the corner cleat, and a second leg received within the second inner channel and terminating at a second end of the corner cleat. A passageway is defined in the corner cleat and extends between the first and second ends. The passageway places the first inner channel in communication with the second inner channel.

    Abstract: New 6xxx aluminum alloy products and methods and systems of making the same are disclosed. A method may include heating a billet of a 6xxx aluminum alloy to a preheat temperature, holding the billet at the preheat temperature for a time sufficient to dissolve at least some precipitate hardening phases of the billet, extruding the billet into an extruded product wherein, during the extruding, both the billet and the extruded product are maintained at or above the preheat temperature, discharging the extruded product from the extrusion apparatus while maintaining the extruded product within 100° F. of a solvus temperature of the 6xxx aluminum alloy, and moving the extruded product from the heating shroud to a quenching apparatus.

    Abstract: New 7xxx aluminum alloys alloys are disclosed. The new 7xxx aluminum alloys may include 5.0-9.0 wt. % Zn, 1.30-2.05 wt. % Mg, 1.10-2.10 wt. % Cu, wherein 2.55≤(wt. % Cu+wt. % Mg)≤3.85, at least one of (i) 0.03-0.40 wt. % Mn and 0.02-0.15 wt. % Zr, wherein 0.05≤(wt. % Zr+wt. % Mn)≤0.50, up to 0.20 wt. % Cr, up to 0.20 wt. % V, up to 0.20 wt. % Fe, up to 0.15 wt. % Si, up to 0.15 wt. % Ti, and up to 75 ppm B, the balance being aluminum, incidental elements and impurities. The new 7xxx aluminum alloys may be in the form of a 7xxx aluminum alloy sheet product having a thickness of from 0.5 to 4.0 mm and comprising at least 15 vol. % recrystallized grains. The new alloys may realize an improved combination of at least two of strength, elongation, fracture behavior and corrosion resistance.

    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.
