Cast aluminum alloys, methods for manufacturing engine parts, engine parts, and uses of cast aluminum alloys for manufacturing engine parts

摘要

The present application relates to a cast aluminum alloy cast by a die casting method, and more particularly to an engine component, particularly a piston for an internal combustion engine, and more particularly to an engine component, particularly a piston for an internal combustion engine, To the use of cast aluminum alloys for producing piston parts for engine parts, in particular internal combustion engines. The cast aluminum alloy includes the following alloying elements: from 9.0 wt% to less than 10.5 wt% silicon, from 0.8 wt% to less than 1.9 wt% nickel, from 1.8 wt% to less than 3.6 wt% copper, from 0.5 wt% to 1.8 By weight or less of magnesium, 0.9 to 1.4% by weight of iron, 0.05 to 0.3% by weight or 0.2% by weight of zirconium and / or vanadium, 0.4 or less of manganese, 0.15 or less of titanium, % Or less phosphorus, aluminum and unavoidable impurities constituting the remainder.
