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.
