PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet resistant to the peeling of plating, exhibiting high strength and preventing edge cracks in rolling.SOLUTION: An aluminum alloy sheet includes, 4.7-6.0 mass% Mg, 0.20 mass% or less Fe, 0.10 mass% or less Si, at least one of 0.005-0.500 mass% Cu and 0.005-0.400 mass% Zn, with 0.500 mass% or less total content of the Cu and the Zn, and the balance Al with inevitable impurities. A dissolved Mg content is 3.8 mass% or more, and 0.2% yield strength is 250-400 MPa.SELECTED DRAWING: None |
