3203-H26 Aluminum

3203-H26 aluminum is 3203 aluminum in the H26 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly 3/4 of the way between annealed (O) and full-hard (H28).

The graph bars on the material properties cards below compare 3203-H26 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.
