    摘要： To provide a method for producing an aluminum ingot whose oxides is reduced by preventing the surface of molten aluminum from being oxidized. The method according to the present invention includes a melting step (melting furnace 1) of melting an aluminum base metal into a molten aluminum or molten aluminum alloy; a holding step (holding furnace 2) of holding the resulting molten aluminum or molten aluminum alloy; a dehydrogenation step (dehydrogenation unit 3) of removing hydrogen gas from the molten aluminum or molten aluminum alloy; a filtration step (filter 4) of removing inclusions from the molten aluminum or molten aluminum alloy; and a casting step (casting device 5) of solidifying the molten aluminum or molten aluminum alloy into a predetermined shape, wherein at least one of the above steps is conducted in the atmosphere of a protective gas containing fluorinating gas, carbon dioxide gas, and nitrogen and/or argon gas.

    摘要： The present invention provides an Al—Mg series alloy sheet of high-Mg with improved press formability and homogeneity which can be applied to automobile outer panels and inner panels. This is an Al—Mg series aluminum alloy sheet having 0.5 to 3 mm in thickness cast by twin-roll continuous casting and cold rolled, comprising over 8% but not more than 14% Mg, 1.0% or less Fe, and 0.5% or less Si with the remainder being Al and unavoidable impurities wherein the mean conductivity of the aluminum alloy sheet is in the range of at least 20 IACS % but less than 26 IACS %, the strength-ductility balance (tensile strength×total elongation) as a material property of the aluminum alloy sheet is 11000 (MPa %) or more, and the homogeneity and press formability of the sheet have been improved.
