Aluminum alloy, cast article of aluminum alloy, and method for producing cast article of aluminum alloy |
摘要 |
An aluminum alloy according to the present invention includes from 4.0 to 6.0% Mg, from 0.3 to 0.6% Mn, from 0.5 to 0.9% Fe, and the balance of Al and inevitable impurities when the entirety is taken as 100% by mass. By appropriately selecting the composition range of Mg, Mn and Fe, it has been possible to micro-finely crystallize Al (Mn, Fe) compounds while inhibiting the growth of primary-crystal Al. As a result, the resulting aluminum alloy is good in terms of the castability, and shows high strength as well as high ductility.
