An aluminum alloy ingot including a Cu content in a range of 0.3 mass % or more and 1.0 mass % or less, a Mg content in a range of 0.6 mass % or more and 1.2 mass % or less, a Si content in a range of 0.9 mass % or more and 1.4 mass % or less, a Mn content in a range of 0.4 mass % or more and 0.6 mass % or less, an Fe content in a range of 0.1 mass % or more and 0.7 mass % or less, a Cr content in a range of 0.09 mass % or more and 0.25 mass % or less, and a Ti content in a range of 0.012 mass % or more and 0.035 mass % or less, with the remainder being made up of Al and unavoidable impurities,

• wherein, in an X-ray diffraction pattern measured using Cu-Kα rays, a peak height of a diffraction peak observed in a diffraction angle 2θ range of 41.6° or more and 42.0° or less is a value smaller than 6 times a standard deviation of a background X-ray intensity in a range of a full width at half maximum of the diffraction peak, and
• wherein, in a heat-treated product after heating at 450° C. for 1 hour, in an X-ray diffraction pattern measured using Cu-Kα rays, a peak height of the diffraction peak observed in a diffraction angle 2θ range of 41.6° or more and 42.0° or less is 15 times or more a standard deviation of the background X-ray intensity in the range of a full width at half maximum of the diffraction peak.
