5457-H25 Aluminum

5457-H25 aluminum is 5457 aluminum in the H25 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly 5/8 of the way between annealed (O) and full-hard (H28).

The graph bars on the material properties cards below compare 5457-H25 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.
