    Abstract: Methods of making new 2xxx aluminum alloy sheet products are disclosed. In one approach, a method comprises artificially aging a 2xxx aluminum alloy in at least two-steps. In one embodiment, the first aging step comprises first aging a 2xxx aluminum alloy at a first temperature of from 300ºF to 450ºF and for a first aging time of from 4 to 120 hours, and second aging the 2xxx aluminum alloy at a second temperature for a second aging time of from 30 minutes to 120 hours, wherein the second temperature is from 20°F to 150°F lower than the first temperature. The new two-step artificial aging step may facilitate an improved combination of properties, such as an improved combination of two or more of strength, ductility, fracture toughness, and corrosion resistance.

    Abstract: A system includes a structural member providing front and back faces, and first and second webs extending between the front and back faces and laterally offset from each other to define a hollow space therebetween. A wire transfer channel is defined at an end of the first web adjacent the front face and extends into the hollow space. A shear block provides a base, a connector portion extending from the base in a first direction, and first and second legs extending from the base in a second direction opposite the first direction, wherein the first and second legs are attachable to the first web to couple the shear block to the structural member.

    Abstract: A sliding door system includes a stationary door frame, a sliding door panel installed in the stationary door frame and movable between closed and open positions, and a handle assembly coupled to the sliding door panel. The handle assembly includes a handle spindle extending into a vertical stile of the sliding door panel, a cam coupled to the handle spindle within the vertical stile and movable between stowed and extended positions, and a handle coupled to the handle spindle and rotatable about a pivot axis extending through the handle spindle between first and second positions. Rotating the handle from the first position to the second position causes the cam to move from the stowed position to the extended position and into engagement with the stationary door frame, whereby the sliding door frame is forced away from the stationary door frame from the closed position to the open position.

    Abstract: [0086] New 6xxx aluminum alloy sheet products are disclosed. In one embodiment, a new 6xxx aluminum alloy sheet product includes from 0.95 to 1.25 wt. % Si, from 0.65 to 0.95 wt. % Mg, wherein (wt. % Mg) / (wt. % Si) is not greater than 0.99: 1, from 0.50 to 0.75 wt. % Cu, from 0.02 to 0.40 wt. % Mn, from 0.03 to 0.26 wt. % Cr, wherein (wt. % Mn) + (wt. % Cr) is at least 0.22 wt. %, from 0.01 to 0.30 wt. % Fe, up to 0.25 wt. % Zn, up to 0.20 wt. % Zr, up to 0.20 wt. % V, and up to 0.15 wt. % Ti, the balance being aluminum, optional incidental elements and impurities. In one embodiment, the new 6xxx aluminum alloy is in the form of a rolled 6xxx aluminum alloy sheet product having a thickness of from 0.5 to 4.0 mm. Products made from the new 6xxx aluminum alloys may realize an improved combination of properties, such as an improved combination of two or more of strength, ductility (elongation), castability, fracture behavior and corrosion resistance.
