Provided is an aluminum alloy for DR can bodies, the alloy having a low earing rate and excellent deep drawing properties even when a batch furnace is used, and a manufacturing method therefor. An aluminum alloy sheet for DR can bodies and a manufacturing method therefor, the aluminum alloy sheet being obtained from an aluminum alloy containing Si: 0.10-0.60 mass% (% below), Fe: 0.10-0.80%, Cu: 0.05-0.25%, Mn: 0.80-1.50%, Mg: 0.80-1.30% and the remainder being obtained from Al and unavoidable impurities and the aluminum alloy sheet being made into a final sheet after passing from an ingot of said aluminum alloy to a hot-rolled sheet and to a process-annealed sheet. In the final sheet, the cube orientation density (CubeO) is 2.00 or more times the random orientation density and the ratio (CubeO/SO) of CubeO to the S orientation density (SO) is 0.40-1.00. After baking, the aluminum alloy sheet has a yield strength of 180-220 MPa and a tensile strength of at least 230 MPa. |
