Questions
Is Brass C260 stronger than Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stronger: its yield strength is 885 MPa against 345 MPa for Brass C260 (2.57x).
Which is lighter, Brass C260 or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is lighter: 4,430 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stiffer: Young's modulus 115 GPa against 110 GPa for Brass C260, so the same part in Titanium Ti-6Al-4V deflects less under the same load.
Which is lighter for the same job, Brass C260 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 C260 | Titanium Ti-6Al-4V |
|---|---|---|
| Stiff rod or tie (tension) | 2x heavier | lighter |
| Stiff beam (bending) | 1.96x heavier | lighter |
| Stiff panel or plate | 1.95x heavier | lighter |
| Strong rod or tie | 4.94x heavier | lighter |
| Strong beam | 3.61x heavier | lighter |
| Strong panel or plate | 3.08x 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 C260 or Titanium Ti-6Al-4V?
Brass C260 conducts heat better: 121 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 µm/m·K for Brass C260.
