1435-H16 Aluminum
1435-H16 aluminum is 1435 aluminum in the H16 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly 3/4 of the way between annealed (O) and full-hard (H18).
It has the second highest strength and second lowest ductility compared to the other variants of 1435 aluminum.
The graph bars on the material properties cards below compare 1435-H16 aluminum to: 1000-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.
