Abstract
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.
