Questions
Is Copper C110 stronger than DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against 69 MPa for Copper C110 (15.9x).
Which is lighter, Copper C110 or DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is lighter: 4,400 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or DMLS Ti-6Al-4V ELI Titanium?
Copper C110 is stiffer: Young's modulus 117 GPa against 110 GPa for DMLS Ti-6Al-4V ELI Titanium, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or DMLS Ti-6Al-4V ELI Titanium?
For the same stiffness or strength: DMLS Ti-6Al-4V ELI 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 | Copper C110 | DMLS Ti-6Al-4V ELI Titanium |
|---|---|---|
| Stiff rod or tie (tension) | 1.9x heavier | lighter |
| Stiff beam (bending) | 1.96x heavier | lighter |
| Stiff panel or plate | 1.98x heavier | lighter |
| Strong rod or tie | 32.3x heavier | lighter |
| Strong beam | 12.8x heavier | lighter |
| Strong panel or plate | 8.09x 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, Copper C110 or DMLS Ti-6Al-4V ELI Titanium?
Copper C110 conducts heat better: 391 W/m·K against 6.6 W/m·K for DMLS Ti-6Al-4V ELI Titanium.
Which expands less with temperature?
DMLS Ti-6Al-4V ELI Titanium expands less: 9 µm/m·K against 16.9 µm/m·K for Copper C110.
