5457-O Aluminum

5457-O aluminum is 5457 aluminum in the annealed condition. It has the lowest strength and highest ductility compared to the other variants of 5457 aluminum. The graph bars on the material properties cards below compare 5457-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.
