Provided is a process of making an aluminum bottle, the process including: obtaining sheet aluminum, the sheet aluminum having a difference between ultimate tensile strength and yield strength between 3.31 thousand pounds per square inch (ksi) and 8.0 ksi, and the sheet aluminum having a yield strength between 33.1 ksi and 42 ksi; cutting a blank from the sheet aluminum; plastically deforming the blank into a cup with three or fewer drawing steps; and necking the cup to form an aluminum bottle with a neck.

Reducing material usage and plastic-deformation steps in the manufacture of aluminum containers

A draw pad reduces instances and the extent of earing when a blank of metal is clamped and punched during a drawing process that results in the formation a cup-shaped body from the blank. A draw pad for a cupping press includes an inner surface that defines a draw aperture that is configured to receive a punch. The draw pad also includes a clamping surface that has a first force concentrating segment disposed circumferentially spaced apart from a second force concentrating segment, where each force concentrating segment includes a first arcuate groove and a second arcuate groove that is disposed concentric and radially spaced apart from the first arcuate groove.
