A method for the mechanical working of metals and alloys which comprises conducting the mechanical working in the presence of an aqueous cooling lubricant having a pH of 6-10 and containing a phosphate ester of the formula <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUB>1</SUB>(oxyalkylene)<SUB>n</SUB>OP(O)(X)(OH) (I),<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>or<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>(HO)<SUB>2</SUB>(O)P-(oxyalkylene)<SUB>m</SUB>OP(O)(OH)<SUB>2</SUB> (II),<?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUB>1 </SUB>is an alkyl group with 1-12 carbon atoms, oxyalkylene is a group containing 2-4 carbon atoms, n is a number from 1-20, X is hydroxyl, R<SUB>1</SUB>O or R<SUB>1</SUB>(oxyalkylene)<SUB>n</SUB>O, where R<SUB>1</SUB>, oxyalkylene and n have the meanings mentioned above, and m is a number from 4-40, or a salt thereof, and an alkenyl substituted succinic acid of the formula <?in-line-formulae description="In-line Formulae" end="lead"?>HOOCCH(R<SUB>2</SUB>)CH<SUB>2</SUB>COOH (III),<?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUB>2 </SUB>is an alkenyl group with 4-10 carbon atoms, or a salt thereof, or a mixture of any of the compounds I, II and III. |
