Design Mechanical and Physical Properties (room temperature)
Converted from the handbook table (ksi, Msi, lb/in³) and rounded to 4 significant figures; dimension bands in inches with mm in parentheses. Bases: A and B are statistical minimums (99 % and 90 % probability at 95 % confidence), S the specification minimum. Grain directions: L longitudinal, LT long transverse, ST short transverse.
| Dimension band | 0.250–0.375 in (6.35–9.525 mm) | 0.376–0.438 in (9.55–11.13 mm) | 0.439–0.500 in (11.15–12.7 mm) | 0.501–0.750 in (12.73–19.05 mm) | 0.751–1.000 in (19.08–25.4 mm) | 1.001–1.500 in (25.43–38.1 mm) | 1.501–2.000 in (38.13–50.8 mm) | |
