Abstract

A method of manufacturing a rolled wear-resistant aluminium alloy product including the steps of: (a) providing a rolling feedstock material of an aluminium alloy having Mg 4.20% to 5.5%, Mn 0.50% to 1.1%, Fe up to 0.40%, Si up to 0.30%, Cu up to 0.20%, Cr up to 0.25%, Zr up to 0.25%, Zn up to 0.30%, Ti up to 0.25%, unavoidable impurities and balance aluminium; (b) heating the rolling feedstock; (c) hot-rolling of the feedstock to an intermediate gauge in a range of 15 mm to 40 mm; (d) hot-rolling of the feedstock from intermediate gauge to a final gauge in a range of 3 mm to 15 mm and wherein the hot-mill exit temperature is in a range of 130-285° C.; (e) cooling of the hot-rolled feedstock to ambient temperature.
