The compositions of the invention may be used to ⁵ are more preferred in the prior art lubricant compositions, metals, especially aluminum and aluminum alloys with malleable hidegjnegmunkálásához.

Paraffin-based, low-viscosity mineral oils, mineral oil-based emulsions, and mixtures of mineral oil and vegetable or animal oils are commonly used as lubricants for punching and light stamping of metal sheets (Eleöd, A., Somfai K., Zakaretechnik, Budapest 1980). Low viscosity petroleum distillates are generally unadulterated, but in some cases fatty acids are added to the lubricating oil to improve lubricity (Evans, E., Silman, H., Swift, Η: Sheet Metal Ind. 24, 1995-2002 and 2209-2213 (1947)). ; Shey, J.: Metallic Deformation Process (Publisher: Marcel Dekker; New York, 1970); Design Handbook, Pressworking Lubricants, Section 21 ASME (published by McGraw-Hill Book Co.,

New York, 1965)]. A variety of polymers having molecular weights ranging from 300 to 50,000 have already been used as additives (C. A, 58).

264 h; 80. 50 219 a; 92. 166,279 x; 94. 124,415 z). A disadvantage of the known lubricants is that in the steps following the technological changes the workpiece will become stained and the lubricant residues can only be removed completely from the workpiece surface by a complicated operation. Moreover, the known lubricants can not be provided on the workpiece temporary (in process), anti-corrosion ^3S Delme.
