2024-T81 Clad flat sheet and plate: MIL-HDBK-5J Design Allowables

Design Mechanical and Physical Properties (room temperature)

As printed in the handbook table. 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.

Effect of Temperature

Percent of the room-temperature value against temperature, digitized from the handbook figures (the shortest exposure of each figure, every 10 °F). Strength curves give the allowable at temperature; "after exposure" curves give the room-temperature property after a soak at that temperature.

Strength allowables at temperature, percent of room temperature

Moduli at temperature

Elongation and exposure effects

Factors in percent of the room-temperature allowable.
