The corrosion behavior of 5086, 5083, and 5456 aluminum alloys in H116 and H117 tempers was evaluated after 2 years of exposure to three marine environments namely, fully submerged in sea water, splash and spray zone, and marine atmosphere. The alloys displayed good corrosion resistance with no exfoliation or pitting observed. Panels of the same alloys in a sensitized condition exposed to the same environments showed some pitting and edge attack but did not indicate a long-term corrosion problem.
