Abstract
Load-bearing additives for lubricants for cold-rolling aluminum, particularly foil rolling down to a thickness below 50 microns, comprise a methyl ester of a saturated straight-chain C10-C14 carboxylic acid, particularly methyl dodecanoate. A saturated straight-chain C10-C14 alcohol, or a saturated straight-chain C8-C14 carboxylic acid may also be present. The lubricants permit greater rolling speeds and improved foil properties during and after annealing.
