Abstract:
1. An aluminum alloy sheet, which is an Al—Mg series aluminum alloy sheet with a thickness of 0.5 to 3 mm cast by twin-roll continuous casting and cold rolled, comprising over 8 and not more than 14 mass % Mg, 1.0 mass % or less Fe, and 0.5 mass % or less Si, wherein the mean conductivity of the aluminum alloy sheet is in the range of at least 20 IACS % but less than 26 IACS %, and the strength-ductility balance (tensile strength×total elongation) as a material property of the aluminum alloy sheet is 14175 (MPa %) or more.
