Abstract (en)

The present invention relates to an aluminium and aluminium alloys cold rolling oil composition comprising a base stock oil and, based on the total weight of the composition, from 0.01 to 5% by weight of a coumpound A having the formula X3-PO3, wherein each X is selected from the group consisting of alkylaryl, aryl-alkyl and aryl groups, wherein each alkyl group has from 3 to 24 carbon atoms and can include heteroatoms like oxygen, nitrogenous or sulfur; each aryl group has from 4 to 10 carbon atoms and can include heteroatoms like oxygen, nitrogen or sulphur; and the alkyl and aryl groups are unsubstitued or substitued with up to 3 halogen substituents. The invention also relates to a process for cold rolling aluminium and aluminium alloys sheets and to the use of the oil composition in an aluminium, aluminium alloys or non ferrous metals cold rolling process. <IMAGE>
