Aluminum Alloys - Mechanical Properties
Mechanical properties of aluminum alloys - tensile strength, yield strength, elastic modulus, and shear modulus for various alloys and tempers. Properties are listed in imperial units (10^6 psi for moduli, 10^3 psi for strengths).
Notes on Units and Tempers
Unit Conversion:
- 1 psi (lb/in²) = 6,894.8 Pa (N/m²)
Temper Designations:
- ANL - Annealing, done after cold working to soften work-hardening alloys
- H - Refers to non-heat-treatable alloys that are "cold worked" or "strain hardened"
- T1 - Cooled from elevated temperature shaping - naturally aged
- T2 - Cooled from elevated temperature shaping - cold worked and naturally aged
- T3 - Solution heat-treated - cold worked and naturally aged to stable condition
- T4 - Solution heat-treated - naturally aged to stable condition
- T5 - Cooled from elevated temperature shaping - artificially aged
- T6 - Solution heat-treated - artificially aged
- T7 - Solution heat-treated - overaged / stabilized
Aluminum Alloy Categories: Aluminum alloys are divided into wrought and cast categories according to how they are produced. The wrought category includes rolling, extruding, drawing, forging, and other specialized processes. Cast alloys are poured molten into sand (sand casting) or high-strength steel (permanent mold or die casting) molds where they solidify to produce the desired shape.
