CAST ALUMINUM ALLOY METHOD FOR PRODUCING AN ENGINE COMPONENT ENGINE COMPONENT AND USE OF A CAST ALUMINUM ALLOY TO PRODUCE 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% 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.
