2017A-T452 Aluminum
2017A-T452 aluminum is 2017A aluminum in the T452 temper. To achieve this temper, the metal is solution heat-treated, stress relieved, then naturally aged. The stress relief is accomplished by compressing the metal by 1-5%.
It has the lowest ductility compared to the other variants of 2017A aluminum.
The graph bars on the material properties cards below compare 2017A-T452 aluminum to: 2000-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.
