Abstract

Method for the mechanical working of Al or Al alloys, in the presence of a water based cooling lubricant contg. lubricating and corrosion inhibiting agents, is characterised in that the cooling lubricant at least at a temp. of 20-70 deg.C is present in the form of a stable soln. The lubricating and corrosion inhibiting agents are a combination of: (a) a carboxylic acid of formula (I) R1COOH (I) where R1 is a 7-22C hydrophobic gp. (b) a tert. alkyl alkanolamine (II) of mol.wt. below 300, and (c) a water soluble organic solubiliser (III) of mol.wt. below 400 and a max. hydrocarbon gp. of 6C; the base/acid equiv. ratio of (II)/(I) being below 1.0, pref. below 0.9. - A concentrate for dilution with water for use as above is also claimed.
