ALUMINIUM CASTING ALLOY, A PROCESS FOR THE MANUFACTURE OF AN ENGINE COMPONENT, ENGINE COMPONENT AND THE USE OF AN ALUMINIUM CASTING ALLOY FOR THE MANUFACTURE OF AN ENGINE COMPONENT

摘要

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 % to10.5 wt %, nickel: 0.8 wt % to1.9 wt %, copper: 1.8 wt % to3.6 wt %, magnesium: 0.5 wt % to 1.8 wt %, iron: 0.9 wt % to1.4 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.
