Abstract
A method of forming a drawn and ironed aluminum container is disclosed herein. The aluminum stock material is initially provided with a thin layer of a particular lubricant applied to one or both surfaces thereof. The lubricant is unemulsified (i) peanut oil and/or (ii) certain oleic acid esters of aliphatic polyhydric alcohols. The method contemplates applying the thin layer of said lubricant to an aluminum stock, cutting a disc and forming a drawn and ironed container utilizing said lubricated disc without additional lubricant being applied to the tooling.
