1080A-H24 Aluminum
1080A-H24 aluminum is 1080A aluminum in the H24 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly halfway between annealed (O) and full-hard (H28).
The graph bars on the material properties cards below compare 1080A-H24 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.
