Questions
Is Aluminum 5052-H32 stronger than Titanium?
Titanium is stronger: its yield strength is 885 MPa against 195 MPa for Aluminum 5052-H32 (4.54x).
Which is lighter, Aluminum 5052-H32 or Titanium?
Aluminum 5052-H32 is lighter: 2,685 kg/m³ against 4,430 kg/m³ for Titanium.
Which is stiffer, Aluminum 5052-H32 or Titanium?
Titanium is stiffer: Young's modulus 115 GPa against 70 GPa for Aluminum 5052-H32, so the same part in Titanium deflects less under the same load.
Which is lighter for the same job, Aluminum 5052-H32 or Titanium?
For the same stiffness or strength: Aluminum 5052-H32 is lighter for a stiff beam (bending), stiff panel or plate; Titanium is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Aluminum 5052-H32 | Titanium |
|---|---|---|
| Stiff rod or tie (tension) | about equal | about equal |
| Stiff beam (bending) | lighter | 29% heavier |
| Stiff panel or plate | lighter | 40% heavier |
| Strong rod or tie | 2.75x heavier | lighter |
| Strong beam | 1.66x heavier | lighter |
| Strong panel or plate | 29% heavier | lighter |
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 5052-H32 or Titanium?
Aluminum 5052-H32 conducts heat better: 138 W/m·K against 6.6 W/m·K for Titanium.
Which expands less with temperature?
Titanium expands less: 9 µm/m·K against 23.8 µm/m·K for Aluminum 5052-H32.
