5110A-H12 Aluminum

5110A-H12 aluminum is 5110A aluminum in the H12 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly a quarter of the way between annealed (O) and full-hard (H18). The graph bars on the material properties cards below compare 5110A-H12 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.
