5457-H38 Aluminum

5457-H38 aluminum is 5457 aluminum in the H38 temper. This is the strongest temper normally produced through the action of strain hardening followed by stabilization. It is closely related to H18. The graph bars on the material properties cards below compare 5457-H38 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.
