Abstract
An aluminum alloy sheet which is high in strength and excellent in heat conductivity, and which can be given an anodic oxide coating with a white color and a suitable yellowishness is provided. An aluminum alloy ingot containing Mg: 0.80 to 1.8 mass %, Fe: 0.05 to 0.30 mass %, Si: 0.20 mass % or less, Cu: 0.03 to 0.15 mass %, Mn: 0.05 to 0.20 mass %, and Cr: 0.05 to 0.15 mass %, restricts Zn to less than 0.15 mass %, and balance of Al and unavoidable impurities is treated by holding it at 560 to 620° C. for 1 to 5 hours, then hot rolled and, either through or not through process annealing, and cold rolled by a final cold rolling reduction of 15 to 95% to obtain an aluminum alloy sheet which has a 0.2% yield strength of 180 MPa or more and a conductivity of 40 (IACS %) or more.
