Claim:
An aluminum alloy for casting consisting of, based upon 100 mass %: 5-9 mass % of silicon (Si), more than or equal to 0.25 and less than or equal to 0.5 mass % of magnesium (Mg), 0.7-1.5 mass % of nickel (Ni), 0.1-0.7 mass % of iron (Fe), from greater than 0.15 to 0.3 mass % of titanium (Ti), less than 0.01 mass % of boron (B), optionally 0.1-0.5 mass % of manganese (Mn), optionally 0.03-0.5 mass % of zirconium (Zr) and/or 0.02-0.5 mass % of vanadium (V), 0.0005-0.003 mass % of calcium (Ca), and the balance being aluminum (Al), wherein Cu is not present in the alloy, or is present only as an inevitable impurity in an amount not to exceed 0.1 mass % of the aluminum alloy, and additional non-metals are only present as inevitable impurities.
