Abstract: The invention relates to a manufacturing process of aluminum alloy beverage cans by «Drawing-Ironing», characterized in that a friction higher between the bodymaker punch and the aluminum sheet than between the ironing die and said aluminum sheet is produced by at least one of the following specificities: An aluminum sheet with an internal surface significantly higher in roughness than the external one Ironing dies with rounded intersections between infeed as well as exit surface and the land, with a smooth surface in the working area and a short width of the land A bodymaker punch with an extra roughness and an isotropic texture. It also relates to a beverage can manufactured by such a process, and characterized in that its reflectance measured at 60° is higher than 73% just after the last ironing step.
