3103-F Aluminum
3103-F aluminum is 3103 aluminum in the as-fabricated (no temper or treatment) condition. It has the lowest strength compared to the other variants of 3103 aluminum. The graph bars on the material properties cards below compare 3103-F aluminum to: 3000-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.
