The application relates to a cast aluminum alloy, to a method for producing an engine component, in particular a piston for an internal combustion engine, wherein a cast aluminum alloy is cast in the gravity permanent-mold casting method, to an engine component, in particular a piston for an internal combustion engine, at least partially consisting of a cast aluminum alloy, and to the use of a cast aluminum alloy to produce an engine component, in particular a piston for an internal combustion engine. The cast aluminum alloy consists of the following alloying elements: silicon: 9.0 wt% to < 10.5 wt%, nickel: 0.8 wt% to < 1.9 wt%, copper: 1.8 wt% to < 3.6 wt%, magnesium: 0.5 wt% to 1.8 wt%, iron: 0.9 wt% to < 1.4 wt%, zirconium and/or vanadium: in each case, 0.05 to <= 0.3 or 0.2%, respectively, manganese: up to <= 0.4 wt%, titanium: up to <= 0.15 wt%, phosphorus: up to <= 0.05 wt%, and aluminum and unavoidable impurities as the remainder. |
