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.
