5454-H28 Aluminum

5454-H28 aluminum is 5454 aluminum in the H28 temper. This is the strongest temper normally produced through the action of strain hardening followed by partial annealing. It is closely related to H18. The graph bars on the material properties cards below compare 5454-H28 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.
