Abstract (en)
An aluminum alloy, which is more resistant to high temperature oxidation-type blistering, comprises: about 0.65-0.9 wt.% silicon, about 4-4.7 wt.% copper, about 0.6-0.9 wt.% manganese, about 0.35-0.55 wt.% magnesium, up to about 0.15 wt.% iron and a balance of aluminum, incidental elements and impurities. By reducing iron content, the invention has reduced scrap rates in some forging part lines to 0%. An improvement in fracture toughness performance was also observed. <IMAGE>
