Abstract

An improved process for cold mechanical working of metallic materials is disclosed, in which a lubricant containing salts of carboxylic acids with more than ten, and preferably 15 to 20, carbon atoms. The lubricant also contains at least one organic solvent with a boiling point below 200.degree. C., and preferably at least one organic solvent with a boiling point below 30.degree. C. In a preferred embodiment, tensides are added to reduce surface tension. The lubricant combines the advantages of solid and liquid lubricants, and permits the cold mechanical working of materials with high tensile strength.
