3105-H24 aluminum is 3105 aluminum in the H24 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly halfway between annealed (O) and full-hard (H18). The graph bars on the material properties cards below compare 3105-H14 aluminum to: 3000-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.

Aluminum 3105 alloy has good forming characteristics. It is suggested that bend radii should be used in one thickness to 2 t range for annealed H12, H14 and H16 tempers. Bend radii of 2 to 7 t should be used for the H18 temper.

Aluminum 3105 alloy can be forged at the temperatures ranging from 372 to 510°C (700 to 950°F). Aluminum 3105 alloy can be hot worked at 205 to 372°C (400 to 700°F) Aluminum 3105 alloy has good cold working characteristics in the harder cold worked tempers. Aluminum 3105 alloy is annealed at 344°C (650°F) followed by cooling in air. Aluminum 3105 alloy can be hardened only by cold working in H12, 14, 16, 18 or 25 tempers.
