摘要
The present invention relates to an aluminium casting alloy having (in % by weight) Cu: 6.0-8.0%, Mn: 0.3-0.055%, 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%, remainder aluminium and unavoidable impurities, and a casting for a combustion engine. The aluminium casting alloy according to the invention has high mechanical properties after a longer operating duration at high temperatures and at the same time can be cast without any problems. Furthermore, the casting according to the invention has optimised mechanical properties during operation at high temperatures and at the same time can be produced in an operationally reliable manner in terms of casting technology.
