Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
DMLS Ti-6Al-4V ELI Titanium is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Brass C360 stronger than DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against 310 MPa for Brass C360 (3.55x).
Which is lighter, Brass C360 or DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is lighter: 4,400 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 96.5 GPa for Brass C360, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.
Which is lighter for the same job, Brass C360 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 | Brass C360 | DMLS Ti-6Al-4V ELI Titanium |
|---|---|---|
| Stiff rod or tie (tension) | 2.2x heavier | lighter |
| Stiff beam (bending) | 2.06x heavier | lighter |
| Stiff panel or plate | 2.02x heavier | lighter |
| Strong rod or tie | 6.85x heavier | lighter |
| Strong beam | 4.49x heavier | lighter |
| Strong panel or plate | 3.64x 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 DMLS Ti-6Al-4V ELI Titanium?
Brass C360 conducts heat better: 116 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 20.5 µm/m·K for Brass C360.
