These are typical values based on standard ASTM/ISO test methods and mill-typical properties. For design calculations, always use the manufacturer's guaranteed minimum properties (typically 95% of typical). For safety-critical applications, also apply appropriate safety factors (2–3× for static loads, 3–5× for dynamic loads).

Temper (heat treatment) state dramatically affects properties — Al 6061-T6 yield is 276 MPa vs 6061-O annealed at 55 MPa. Processing (cast vs wrought vs extruded) also matters. Alloy additions change strength, corrosion resistance, and machinability. Always specify the exact temper and condition on drawings.

First identify your 2–3 critical properties (e.g., tensile strength, density, HDT). Scan the table for materials meeting those thresholds. Then check manufacturability (machinability rating) and cost. Finally, verify specific grade properties on manufacturer datasheets before finalizing.

This table shows short-term properties. For long-term, cyclic, or creep loading, consult manufacturer datasheets — most alloys show significant strength reduction under 10,000+ hour loading or millions of stress cycles. Our engineering team can recommend appropriate derating factors for your application.
