Questions
Is Brass C360 stronger than Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stronger: its yield strength is 885 MPa against 310 MPa for Brass C360 (2.85x).
Which is lighter, Brass C360 or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is lighter: 4,430 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stiffer: Young's modulus 115 GPa against 96.5 GPa for Brass C360, so the same part in Titanium Ti-6Al-4V deflects less under the same load.
Which is lighter for the same job, Brass C360 or Titanium Ti-6Al-4V?
For the same stiffness or strength: Titanium Ti-6Al-4V 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 Ti-6Al-4V |
|---|---|---|
| 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 Ti-6Al-4V?
Brass C360 conducts heat better: 116 W/m·K against 6.6 W/m·K for Titanium Ti-6Al-4V.
Which expands less with temperature?
Titanium Ti-6Al-4V expands less: 9 µm/m·K against 20.5 µm/m·K for Brass C360.
