摘要：

PROBLEM TO BE SOLVED: To provide an Al alloy casting product where generation of cavity causing pressure leakage is avoided and a cast structure is sufficiently micronized despite of solidification speed, and a manufacturing method therefor.SOLUTION: A molten metal of Al alloy containing Si of 4.0 to 10.0 mass%, Fe of 0.15 to 0.50 mass%, Ca of 7 to 15 ppm and P of 3 to 8 ppm is solidified to obtain an Al alloy casting product having an area ratio of an Al-Si-Fe-Ca-P compound 10 deposited in area of 1.5 mm×1.8 mm of less than 10% in total part.
