8011A-O Aluminum

8011A-O aluminum is 8011A aluminum in the annealed condition. The graph bars on the material properties cards below compare 8011A-O aluminum to: otherwise unclassified aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
