To provide an aluminum alloy sheet for a can body, in which production of cracks upon rolling is suppressed, the occurrence rate of barrel breakage is suppressed, and thrusting strength is made high as well.
The aluminum alloy sheet has a composition comprising, by mass, 0.8 to 1.1% Mn, 1.3 to 1.7% Mg, 0.25 to 0.4% Si, 0.3 to 0.55% Fe, 0.3 to 0.45% Cu, 0.6 to 0.8% Si+Cu, Cu content ≥ Si content, and the balance Al. The aluminum alloy sheet has a sheet thickness of 0.240 to 0.265 mm, material tensile strength of ≤325 MPa, stock proof stress of 285 to 310 MPa, material elongation of 2.5 to 4.5%, material proof stress after baking of ≥280 MPa, (AB TS)-(AB YS) after material baking is ≥37 MPa, tensile strength at the barrel part of a can body is 350 to 410 MPa, elongation of the barrel part is 4.5 to 5%, the change of TS by baking is ≥10 MPa, and the change of YS by baking (H YS-AB YS) is ≤10 MPa.
