Abstract
An aluminum alloy has a chemical composition that contains Sc: 0.01 mass % or more and 0.40 mass % or less, Mg: 0 mass % or more and 2.5 mass % or less, and Zr: 0 mass % or more and 0.4 mass % or less, the remainder being Al and unavoidable impurities. The compressive-deformation resistance, which is calculated based on the true stress when the aluminum alloy is deformed by compressing at a temperature of 450° C. and a strain rate of 1 s−1, is 62 MPa or less.
