摘要:
An aluminum alloy for a die casting, used as the material of parts of an automotive vehicle. The aluminum alloy consists essentially of Si in an amount ranging from 10 to 12% by weight, Mg in an amount ranging from 0.15 to 0.50% by weight, Mn in an amount ranging from 0.5 to 1.0% by weight, Fe in an amount of not more than 0.15% by weight, Ti in an amount of not more than 0.1% by weight, Sb in an amount ranging from 0.05 to 0.20% by weight, B in an amount ranging from 0.005 to 0.02%, and balance consisting of aluminum and inevitable impurities. Sb in the amont ranging from 0,05 to 0,20% by weight could be replaced with Sr in an amount from 0,005 to 0,020% by weight.
