    摘要： A method of producing an aluminum product having high formability, high fracture toughness, high strength and improved corrosion resistance, the method comprising: (a) providing stock including an aluminum base alloy consisting essentially of about 0.7 to 1.0 wt.% silicon, not more than about 0.3 wt.% iron, not more than about 0.5 wt.% copper, about 0.8 to 1.1 wt.% magnesium, about 0.3 to 0.4 wt.% manganese, and about 0.5 to 0.8 wt.% zinc, the remainder substantially aluminum, incidental elements and impurities; (b) homogenizing the stock; (c) hot rolling; (d) solution heat treating; (e) cooling by quenching; and (f) artificially aging to produce a T6 temper in the aluminum product. The figure shows ductility loss as a function of the amount of copper in alloys containing either manganese or chromium and zinc relative to alloy 6013.

    摘要： Apparatus and a process for the high-speed coiling of an aluminum strip. The high speed coiling can be accomplished throughout a continuous casting process without slowing the coiling as the present invention enables the transfer of the moving strip from one coil to an empty mandrel without slowing the line speed. Since line speeds can be approximately 3600 feet per minute, this represents an advance in process technology. Generally, the transfer of the moving strip is accomplished using a very high speed knife (28), and a belt wrapper (24). The moving strip is accumulated on one mandrel (2) to form a coil, the coil is moved away from the knife and a second mandrel (4) is brought into position. The knife is positioned at the moving aluminum strip and accelerated to cut the strip and deflect it to a tucking roll with a moving belt. The moving strip is forced around the second mandrel and starts to wind to form a coil. The completed coil is removed and the process is repeated.

    摘要： Lithium feed to an aluminium-lithium alloy production system is achieved at a highly controlled rate by advancing a plunger (25) at a predetermined volumetric rate into a body of molten lithium retained in a holding vessel (20) to displace the lithium toward an overflow port (33) through which it is fed into a mixing vessel (67) where it is combined with the molten aluminium. Control of the aluminium feed rate is achieved by maintaining a constant head height upstream of an orifice (68). The thus metered streams of molten lithium and aluminium are then combined in a vortex bowl, whose outlet then feeds the molten alloy to a casting station.
