FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly to aluminum alloys, which can be used to produce thermally loaded parts for automotive industry by extrusion, forging or casting into multiple molds. Aluminium alloy comprises, by wt. %: 0.2–1.8 Si, 0.2–1.8 Mg, 0.8–2.5 Mn, 0.2–1.5 Fe, 0.05–0.75 Zr, 0.03–0.18 Ti, optionally one or more of the following elements: max. 0.1 Cr, max. 0.05 Cu, 0.2–1.8 Zn, 0.02–0.5 Er; and, optionally, 0.01–0.2 grain milling additive containing Ti and B; balance is aluminum and unavoidable impurities.
EFFECT: invention is aimed at obtaining alloy with high heat resistance at good hardness values.
