FIELD: plastic working of metals, possibly cold rolling or drawing aluminum blanks.
SUBSTANCE: tool has shaping surface designed for deforming aluminum blank at relative motion of said blank and tool. Shaping surface of tool is made of material preventing aluminum sticking onto it, for example from nickel base alloy containing more than 74 mass % of nickel. Tool may be in the form of roll or drawing die. Nickel base alloy may contain cobalt in quantity not exceeding 0.7 mass %. Total content of nickel and cobalt in such alloy consists 97.6 mass %, impurities are the balance.
EFFECT: increased useful life period of tool, improved quality of part formed of such blank.
