Questions

Mechanical

Is DMLS Ti-6Al-4V ELI Titanium stronger than Titanium Ti-6Al-4V?

DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against 885 MPa for Titanium Ti-6Al-4V (24%).

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

DMLS Ti-6Al-4V ELI Titanium is lighter: 4,400 kg/m³ against 4,430 kg/m³ for Titanium Ti-6Al-4V.

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

Titanium Ti-6Al-4V is stiffer: Young's modulus 115 GPa against 110 GPa for DMLS Ti-6Al-4V ELI Titanium, so the same part in Titanium Ti-6Al-4V deflects less under the same load.

Which is lighter for the same job, DMLS Ti-6Al-4V ELI Titanium or Titanium Ti-6Al-4V?

For the same stiffness or strength: DMLS Ti-6Al-4V ELI Titanium is lighter for a strong rod or tie, strong beam, strong panel or plate; Titanium Ti-6Al-4V is lighter for a stiff rod or tie (tension), stiff beam (bending).

Part that must beDMLS Ti-6Al-4V ELI TitaniumTitanium Ti-6Al-4V
Stiff rod or tie (tension)3% heavierlighter
Stiff beam (bending)1% heavierlighter
Stiff panel or plateabout equalabout equal
Strong rod or tielighter25% heavier
Strong beamlighter16% heavier
Strong panel or platelighter12% heavier

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, DMLS Ti-6Al-4V ELI Titanium or Titanium Ti-6Al-4V?

Titanium Ti-6Al-4V stretches further before it breaks: 16% elongation at break against 8.7% for DMLS Ti-6Al-4V ELI Titanium.

Thermal

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

DMLS Ti-6Al-4V ELI Titanium conducts heat better: 6.6 W/m·K against 6.6 W/m·K for Titanium Ti-6Al-4V.

Which expands less with temperature?

DMLS Ti-6Al-4V ELI Titanium expands less: 9 µm/m·K against 9 µm/m·K for Titanium Ti-6Al-4V.
