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.

Abstract: A necking tool for manufacturing of metal beverage cans, the necking tool being a cemented carbide comprising in wt % of about 18 to about 63 WC, of about 21 to about 30 TiC, of about 0 to about 27 TiN, of about 0 to about 12 NbC, of about 0 to 2 Cr3C2, of about 8 to about 14 Co and of about 0 to about 6 Ni.

Abstract: There is disclosed a cemented carbide tool containing tungsten carbide, titanium carbide, nickel and cobalt, molybdenum and chromium. The composition of the materials provides a good resistance to corrosion as well as high hardness and wear resistance. These properties are particularly interesting for the manufacture of tools for coldforming operations. Cold forming tools made with these materials have steady performance over a long period of time.

Abstract: A cemented carbide tool containing tungsten carbide, titanium carbide, niobium carbide, possibly TaC, cobalt, chromium and possibly nickel, iron, molybdenum is disclosed. The composition of the materials provides a lighter material than usual, combined with a good resistance to corrosion as well as high hardness and wear resistance. These properties are particularly interesting for the manufacture of punch tools for cold forming operations. Cold forming tools made with these materials will have much better performance, particularly more steady performance and much longer lifetime. A method of cold forming and drawing, particularly deep drawing and ironing process of aluminum and steel beverage can manufacturing, is also disclosed.
