3103-H15 Aluminum

3103-H15 aluminum is 3103 aluminum in the H15 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly 5/8 of the way between annealed (O) and full-hard (H18). The graph bars on the material properties cards below compare 3103-H15 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.
