1050A-H112 Aluminum

1050A-H112 aluminum is 1050A 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.

It has the second lowest strength compared to the other variants of 1050A aluminum.

The graph bars on the material properties cards below compare 1050A-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.
