Abstract
A method of metalworking including the step of applying to a metal object a synthetic aqueous lubricant composition. The composition comprises a water-soluble mixture of polyoxypropylene-polyoxyethylene-polyoxypropylene block copolymers, a water-soluble carboxylic acid, a water-soluble alkanolamine and water. The metalworking method preferably includes a step of either hot rolling or cold rolling. The method is especially suitable for use on aluminum and aluminum alloy material.
