5252-H24 Aluminum

5252-H24 aluminum is 5252 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). It has the lowest strength compared to the other variants of 5252 aluminum.

The graph bars on the material properties cards below compare 5252-H24 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.
