HIGH-FIRE RESISTANCE CASTING ALUMINIUM ALLOY AND CAST PRODUCTS FOR INTERNAL COMBUSTION ENGINES, CAST FROM SAID ALLOY Russian patent published in 2017 - IPC C22C21/14 

FIELD: metallurgy.

SUBSTANCE: invention relates to cast alloys based on aluminium and can be used for making internal combustion engine parts. Alloy contains, wt%: Cu 6.0–8.0, Mn 0.3–0.55, Zr 0.18–0.25, Si 3.0–7.0, Ti 0.05–0.2, Sr up to 0.03, V up to 0.04, Fe up to 0.25, balance is aluminium and unavoidable impurities. Casting aluminium alloy has high mechanical properties after a long period of operation at high temperatures and can also fill mould well during casting.

EFFECT: cast products according to present invention have optimised mechanical properties during operation at high temperatures and can also be reliably made by casting.
