Questions
Is Aluminum 2024-T351 stronger than Aluminum 5052-H32?
Aluminum 2024-T351 is stronger: its yield strength is 324 MPa against 195 MPa for Aluminum 5052-H32 (1.66x).
Which is lighter, Aluminum 2024-T351 or Aluminum 5052-H32?
Aluminum 5052-H32 is lighter: 2,685 kg/m³ against 2,770 kg/m³ for Aluminum 2024-T351.
Which is stiffer, Aluminum 2024-T351 or Aluminum 5052-H32?
Aluminum 2024-T351 is stiffer: Young's modulus 73.1 GPa against 70 GPa for Aluminum 5052-H32, so the same part in Aluminum 2024-T351 deflects less under the same load.
Which is lighter for the same job, Aluminum 2024-T351 or Aluminum 5052-H32?
For the same stiffness or strength: Aluminum 2024-T351 is lighter for a stiff rod or tie (tension), strong rod or tie, strong beam, strong panel or plate; Aluminum 5052-H32 is lighter for a stiff panel or plate.
| Part that must be | Aluminum 2024-T351 | Aluminum 5052-H32 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 1% heavier |
| Stiff beam (bending) | about equal | about equal |
| Stiff panel or plate | 2% heavier | lighter |
| Strong rod or tie | lighter | 1.61x heavier |
| Strong beam | lighter | 36% heavier |
| Strong panel or plate | lighter | 25% heavier |
For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Which conducts heat better, Aluminum 2024-T351 or Aluminum 5052-H32?
Aluminum 5052-H32 conducts heat better: 138 W/m·K against 120 W/m·K for Aluminum 2024-T351.
Which expands less with temperature?
Aluminum 2024-T351 expands less: 22.9 µm/m·K against 23.8 µm/m·K for Aluminum 5052-H32.
