Questions
Is Brass C360 stronger than Titanium?
Titanium is stronger: its yield strength is 885 MPa against 310 MPa for Brass C360 (2.85x).
Which is lighter, Brass C360 or Titanium?
Titanium is lighter: 4,430 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or Titanium?
Titanium is stiffer: Young's modulus 115 GPa against 96.5 GPa for Brass C360, so the same part in Titanium deflects less under the same load.
Which is lighter for the same job, Brass C360 or Titanium?
For the same stiffness or strength: Titanium is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brass C360 | Titanium |
|---|---|---|
| Stiff rod or tie (tension) | 2.28x heavier | lighter |
| Stiff beam (bending) | 2.09x heavier | lighter |
| Stiff panel or plate | 2.03x heavier | lighter |
| Strong rod or tie | 5.48x heavier | lighter |
| Strong beam | 3.86x heavier | lighter |
| Strong panel or plate | 3.24x 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, Brass C360 or Titanium?
Brass C360 conducts heat better: 116 W/m·K against 6.6 W/m·K for Titanium.
Which expands less with temperature?
Titanium expands less: 9 µm/m·K against 20.5 µm/m·K for Brass C360.
