Abstract:
An aluminum alloy material comprises: Si: less than 0.2 mass %, Fe: 0.1 to 0.3 mass %, Cu: 1.0 to 2.5 mass %, Mn: 1.0 to 1.6 mass %, and Mg: 0.1 to 1.0 mass %, the balance being Al and incidental impurities. A number density of Al—Mn compound having a circle equivalent diameter of not less than 0.1 μm is not less than 1.0×105 mm−2, and a number density of Al2Cu having a circle equivalent diameter of not less than 0.1 μm is not more than 1.0×105 mm−2.
