Abstract:
An aluminum alloy material exhibiting excellent bendability can be produced without performing a straightening step, and can be bent without developing orange peel. The aluminum alloy material is a T4-tempered material formed of an Al—Cu—Mg—Si alloy including 1.0 to 2.5 mass % of Cu, 0.5 to 1.5 mass % of Mg, and 0.5 to 1.5 mass % of Si, with the balance being aluminum and unavoidable impurities, a matrix that forms an inner part of the aluminum alloy material having a microstructure formed by recrystallized grains having an average crystal grain size of 200 μm or less, and the aluminum alloy material having a ratio of tensile strength/yield strength determined by a tensile test of 1.5 or more.
