Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "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

Mechanical

Is Copper C10100 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 C10100 (15.9x).

Which is lighter, Copper C10100 or DMLS Ti-6Al-4V ELI Titanium?

DMLS Ti-6Al-4V ELI Titanium is lighter: 4,400 kg/m³ against 8,941 kg/m³ for Copper C10100.

Which is stiffer, Copper C10100 or DMLS Ti-6Al-4V ELI Titanium?

Copper C10100 is stiffer: Young's modulus 117 GPa against 110 GPa for DMLS Ti-6Al-4V ELI Titanium, so the same part in Copper C10100 deflects less under the same load.

Which is lighter for the same job, Copper C10100 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 beCopper C10100DMLS Ti-6Al-4V ELI Titanium
Stiff rod or tie (tension)1.91x heavierlighter
Stiff beam (bending)1.97x heavierlighter
Stiff panel or plate1.99x heavierlighter
Strong rod or tie32.4x heavierlighter
Strong beam12.9x heavierlighter
Strong panel or plate8.11x heavierlighter

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 is more ductile, Copper C10100 or DMLS Ti-6Al-4V ELI Titanium?

Copper C10100 stretches further before it breaks: 45% elongation at break against 8.7% for DMLS Ti-6Al-4V ELI Titanium.

Thermal

Which conducts heat better, Copper C10100 or DMLS Ti-6Al-4V ELI Titanium?
