Abstract: A two- or a one-step process and composition which coats metal workpiece surfaces (aluminum, copper, steel, stainless steel, etc.) with a thin lubricant film capable of allowing the metal to be deformed at room temperature. The lubricant consists essentially of polymers, dispersants, high molecular weight waxes and insoluble metallic stearates. With some ferrous surfaces, a separate coating layer is simultaneously formed (in the one-step process) or pre-formed (in the two-step process) at the metal interface, acting as a base for the lubricant. The process, after pickling in a mineral acid to remove scale and oxides, comprises the step(s) of immersing the workpiece either once or twice. The workpiece is then dried in a heated, forced air dryer.
