- Price index: $$ (1–5, 6061-T6 = $)

## Mechanical properties (typical values, not certified minimums)

| Property | Value |
|---|---|
| Tensile strength | 470 MPa |
| Yield strength | 325 MPa |
| Hardness | 120 HB |
| Density | 2.78 g/cm³ |
| Machinability | ★★★☆☆ (3/5) |
| Corrosion resistance | ★★☆☆☆ (2/5) |

## When to choose it

Choose 2024 for fatigue-critical, damage-tolerant structure: cracks grow slowly and predictably, and it frequently outlasts both 6061 and 7075 under cyclic loading.

## When to look elsewhere

Bare 2024 is the least corrosion-resistant common aluminum — never ship it unprotected into humid service; always anodize, chromate or prime. Avoid welding entirely.

## Typical applications

- Aircraft structural fittings and splices
- Cyclically loaded actuator brackets
- Legacy aerospace replacement parts
- Vibration test rigs
