5383-H321 Aluminum

5383-H321 aluminum is 5383 aluminum in the H321 temper. To achieve this temper, the metal is strain hardened, and then stabilized, to a strength that is roughly a quarter of the way between annealed (O) and full-hard (H38). The treatment process also has to leave the metal with a certain degree of resistance to intergranular and exfoliation corrosion.

The graph bars on the material properties cards below compare 5383-H321 aluminum to: 5000-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.
