3105-H24 aluminum is 3105 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 barss on the material properties cards below compare 3105-H24 aluminum to: 3000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bars means this is the highest value in the relevant set. A half-full bars means it’s 50% of the highest, and so on.
