ABSTRACT LUBRICATING COMPOSITION AND METHOD A lubricating composition for press forming consists of a lubricant dissolved or dispersed in a volatile liquid medium, wherein the lubricant comprises at least one ester of a polyhydric alcohol having two or three hydroxyl groups of which one or two are esterified with a long chain carboxylic acid and has a melting point above ambient temperature but low enough to permit removal from a metal surface by an aqueous alkaline cleaner. The composition is useful for forming structures of shaped aluminium components on a production line.
