WIPO Patent Application WO/2023/171576
Kind Code:
A9
Abstract:
Provided is an aluminum alloy plate for a can lid, said plate being capable of having both high strength and high toughness while containing a scrap material derived from cans. In one aspect of the present disclosure, the aluminum alloy plate for a can lid contains 0.10 mass% to 0.60 mass% of Si, 0.20 mass% to 0.70 mass% of Fe, 0.10 mass% to 0.40 mass% of Cu, 0.5 mass% to 1.2 mass% of Mn, and 1.1 mass% to 4.0 mass% of Mg, wherein the 0.2 proof strength σ0.2, the tensile stress σB, and the average value σfm of the 0.2 proof stress and the tensile stress satisfy formula (1). (1): σfm/(σ0.2/σB) ≥ 350 MPa
