Abstract

Mechanical working of cast iron is performed in the presence of an aqueous metalworking composition containing an organic copper (II) complex and an iron corrosion inhibitor. An aqueous concentrate, which after dilution with water is suitable for application in mechanical working of cast iron, contains 1-50% copper (II) complex with such a Cu.sup.2+ -content of 0.5-20%, 1-50% iron corrosion inhibitor, 0-50% lubricant, 0-20% pH-regulators, bactericides and solubilizing agents and 10-70% water.
