2014A-O Aluminum

2014A-O aluminum is 2014A aluminum in the annealed condition. It has the highest ductility compared to the other variants of 2014A aluminum. The graph bars on the material properties cards below compare 2014A-O aluminum to: 2000-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.
