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 | 0–2 in (0–50.8 mm) | 2.001–4.000 in (50.83–101.6 mm) | 4.001–5.000 in (101.6–127 mm) | 5.001–6.000 in (127–152.4 mm) | |
