<p>PROBLEM TO BE SOLVED: To produce an aluminum alloy-laminated sheet having strength equal to that of the conventional end part made of a 5182 alloy, furthermore satisfying excellent blowup resistance, moreover capable of using a used can for drinking as the raw material, moreover free from the formation of harmful substances at the time of producing the stock and in a recycling stage and suitable for use for the end part of a can for drinking. SOLUTION: In an aluminum alloy-laminated sheet obtd. by laminating a thermoplastic resin film on one side or both sides of an aluminum alloy base sheet, the aluminum alloy base sheet has a compsn. contg., by weight, 0.6 to 1.2% Mn, 0.5 to 3.2% Mg, 0.2 to 0.5% Si, 0.3 to 0.5% Cu, 0.3 to 0.6% Fe, and the balance aluminum with inevitable impurities, its proof strength is regulated to >=300 MPa, and also, the ratio of the tenssile strength to the proof strength is regulated to >=1.15.</p> |
