Abstract
The present invention provides a bright aluminum alloy which has high mechanical properties and in which the occurrence of uneven color is also suppressed to a high degree when an aluminum alloy die-cast material thereof that includes tungsten is subjected to anodization treatment. Also provided is a bright aluminum alloy die-cast material that is manufactured using said bright aluminum alloy. The aluminum alloy pertaining to the present invention includes 0.5-3.0% by mass of Mn, 0.1-2.0% by mass of Mg, 0.01-1.0% by mass of W, and 0.05-2.0% by mass of Si, the balance being aluminum and unavoidable impurities.
