Abstract

A method for producing an engine component, more particularly a piston for an internal combustion engine, in which an aluminum alloy is cast using the gravity die casting method is provided. The aluminum alloy comprises: 9 to ≤10.5% by weight silicon, >2.0 to <3.5% by weight nickel, >3.7 to 5.2% by weight copper, <1% by weight cobalt, 0.5 to 1.5% by weight magnesium, 0.1 to 0.7% by weight iron, 0.1 to 0.4% by weight manganese, >0.1 to <0.2% by weight zirconium, >0.1 to <0.2% by weight vanadium, 0.05 to <0.2% by weight titanium, 0.004 to 0.008% by weight phosphorus, with aluminum and unavoidable impurities constituting the rest. An engine component, in particular a piston, wherein the engine component consists, at least partially, of the aluminum alloy, and the use of an aluminum alloy to produce the engine component, is also provided.
