<p>PROBLEM TO BE SOLVED: To provide a can in which the service range of the aluminum alloy to be used is expanded to the high strength material and the bulge workability is excellent. SOLUTION: An aluminum can body mainly consists of aluminum containing, by weight, 0.05-1.5% Si, 0.05-1.0% Fe, 0.2-5.5% Mg, 0.35-0% Cu, 2.0-0% Mn, the minimum thickness of a side wall part of the can body is 0.06-0.16mm, and the minimum thickness of the can body part is <=70% of the thickness of an original sheet, and the can body ultimate deformation capacityεw to be defined asεw=1n(tb/tw), isεw<=0.06F-2.1, where F is the maximum tensile load (kgf), tb is the thickness (mm) of a ductile fracture surface of the test piece obtained from the measured value of the test piece of 6mm in width of a parallel part, and tw (mm) in thickness in which the circumferential direction of the can obtained from the can body in the vicinity of H/2 is the longitudinal direction where H is the can height (mm), and the direction orthogonal to the rolling direction of can bottom is the center, and a two-piece seamless aluminum can body comprising the can body wall in which 15<=f<30, andεw<=-0.7, and the present invention also relates to a manufacturing method.</p> |
