1080A-H112 Aluminum
1080A-H112 aluminum is 1080A aluminum in the H112 temper. This temper is actually just a variation on F (as-fabricated) that allows for the possibility of very limited strain hardening or heat treatment, under certain conditions.
The graph bars on the material properties cards below compare 1080A-H112 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.
