Abstract
An aluminum alloy preform having an outer surface portion prelubricated with a film of a water-microemulsifiable lubricant composition comprising an oil, an anionic surfactant, a non-ionic cosurfactant, and optionally a C.sub.10 -C.sub.36 mono- or dicarboxlyic acid. The lubricant composition is dissolved in an organic solvent (preferably hexane) and applied to the preform. The solvent evaporates, leaving a water-microemulsifiable lubricant film. The lubricated product is readily washable with water to microemulsify the lubricant film into a microemulsion.
