Patent number: 6537392Abstract: There is claimed an aerospace alloy having improved corrosion resistance performance, particularly intergranular corrosion resistance. The alloy consisting essentially of: about 0.6-1.15 wt. % silicon, about 0.6-1.0 wt. % copper, about 0.8-1.2 wt. % magnesium, about 0.55-0.86 wt. % zinc, less than about 0.1 wt. % manganese, about 0.2-0.3 wt. % chromium, the balance aluminum, incidental elements and impurities. While it is preferably made into sheet or plate product forms, it can also be extruded. Products made from this alloy exhibit at least about 5% greater yield strength and about 45% or greater resistance to intergranular corrosion attack than their 6013-T6 counterparts, as measured by average depth of corrosion after 24 hours exposure to an aqueous NaCl—H2O2 solution per ASTM Standard G110 (1992).Type: GrantFiled: June 1, 2001Date of Patent: March 25, 2003Assignee: Alcoa Inc.Inventors: Paul E. Magnusen, Edward L. Colvin, Roberto J. Rioja
