5154-O Aluminum
5154-O aluminum is 5154 aluminum in the annealed condition. It has the highest ductility compared to the other variants of 5154 aluminum. The graph bars on the material properties cards below compare 5154-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.
