Abstract: An aluminum alloy sheet has a composition comprising 0.5% or less by mass of Si, 0.7% or less by mass of Fe, 0.3% or less by mass of Cu, 0.4 to 1.5% by mass of Mn, 0.7 to 1.5% by mass of Mg and an balance comprising Al and inevitable impurities. A degree of integration in the Goss orientation is 1.5 or more. A degree of integration in the Cu orientation is 6.2 or less. A tensile strength is 200 to 310 MPa. An areal ratio of an α-Al—Fe—Mn—Si based intermetallic compound with an equivalent circle diameter of 0.5 μm or more is preferably 2.6% or more.

Abstract: An aluminum alloy sheet for a beverage can body has a composition including 0.10 mass % or more and 0.70 mass % of Si; 0.10 mass % or more and 0.80 mass % or less of Fe; 0.10 mass % or more and 0.30 mass % or less of Cu; 0.50 mass % or more and 1.50 mass % or less of Mn; 1.00 mass % or more and 1.50 mass % or less of Mg, and a balance including Al and inevitable impurities. An n-value in an equivalent plastic strain range of 0.01 to 0.03 is 0.049 or greater. An n-value in an equivalent plastic strain range of 0.3 to 1.1 is 0.063 or less.
