1435-O Aluminum

1435-O aluminum is 1435 aluminum in the annealed condition. It has the lowest strength and highest ductility compared to the other variants of 1435 aluminum. The graph bars on the material properties cards below compare 1435-O aluminum to: 1000-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.
