Abstract

The present application relates to an aluminum alloy, in particular a cast aluminum alloy, a method for producing an engine component, in particular a piston for an internal combustion engine, in which an aluminum alloy is cast using the gravity die casting method, and an engine component, in particular a piston for an internal combustion engine, consisting at least partially of an aluminum alloy. The aluminum alloy consists of the following alloy elements:

silicon: 10% by weight to <13% by weight,nickel: up to <0.6% by weight,copper: 1.5% by weight to <3.6% by weight,magnesium: 0.5% by weight to 1.5% by weight,iron: 0.1% by weight to 0.7% by weight,manganese: 0.1 to 0.4% by weight,zirconium: >0.1 to <0.3% by weight,vanadium: >0.08 to <0.2% by weight,titanium: 0.05 to <0.2% by weight,phosphorus: 0.0025 to 0.008% by weight,and the remainder being aluminum and unavoidable impurities. Furthermore, the microstructure of the alloy has spheroidized primary precipitates.
