1. A method of forming a slug of a recycled aluminum alloy for use in manufacturing a metallic bottle in an impact extrusion process, the recycled aluminum alloy of the slug having a mechanical strength such that integral threads can be formed on the metallic bottle for a roll on pilfer proof (ROPP) closure, the method comprising:
melting a scrap aluminum material;
blending the melted scrap aluminum material with a first aluminum alloy to form the recycled aluminum alloy, wherein said recycled aluminum alloy comprises about 80 wt. % of scrap aluminum material, and wherein the recycled aluminum alloy is adapted for use in an impact extrusion process and the recycled aluminum alloy has a mechanical strength such that the integral threads for the roll on pilfer proof (ROPP) closure can be formed on a metallic bottle formed from the slug in the impact extrusion process;
casting the recycled aluminum alloy into a slab;
rolling the slab to a specified thickness;
cooling the slab; and
punching a slug from the cooled slab.
