5657-H25 Aluminum
5657-H25 aluminum is 5657 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).
It has the second lowest strength and second highest ductility compared to the other variants of 5657 aluminum.
The graph bars on the material properties cards below compare 5657-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.
