5026-O Aluminum
5026-O aluminum is 5026 aluminum in the annealed condition. The graph bars on the material properties cards below compare 5026-O aluminum to: 5000-series alloys (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.
