摘要： PROBLEM TO BE SOLVED: To provide a casting aluminum alloy for manufacturing a casting of an aluminum alloy, which causes little irreversible dimensional change and has superior dimensional stability.
SOLUTION: The casting aluminum alloy includes Si, the balance being mainly Al, and further 0.0001 to 0.5 mass% in total of Si-solid-solution-inhibiting elements with respect to 100% of the total mass, which reduce an amount of Si dissolved in an Al-based matrix, by promoting crystallization of Si from a molten alloy, in a solidification step of cooling and solidifying the molten casting aluminum alloy, to impart the casting of the aluminum alloy the superior dimensional stability even in an as-cast condition. The addition of the Si-solid-solution-inhibiting elements reduces the amount of Si dissolved in the Al-based matrix, reduces the amount of precipitated Si which causes the irreversible dimensional change, and thereby enhances the dimensional stability of the casting of the aluminum alloy.
