Questions

Mechanical

Is Aluminum 3003-O stronger than DMLS Ti-6Al-4V ELI Titanium?

DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against 40 MPa for Aluminum 3003-O (27.5x).

Which is lighter, Aluminum 3003-O or DMLS Ti-6Al-4V ELI Titanium?

Aluminum 3003-O is lighter: 2,730 kg/m³ against 4,400 kg/m³ for DMLS Ti-6Al-4V ELI Titanium.

Which is stiffer, Aluminum 3003-O or DMLS Ti-6Al-4V ELI Titanium?

DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 69 GPa for Aluminum 3003-O, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.

Which is lighter for the same job, Aluminum 3003-O or DMLS Ti-6Al-4V ELI Titanium?

For the same stiffness or strength: Aluminum 3003-O is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; DMLS Ti-6Al-4V ELI Titanium is lighter for a strong rod or tie, strong beam, strong panel or plate.

Part that must beAluminum 3003-ODMLS Ti-6Al-4V ELI Titanium
Stiff rod or tie (tension)lighter1% heavier
Stiff beam (bending)lighter28% heavier
Stiff panel or platelighter38% heavier
Strong rod or tie17.1x heavierlighter
Strong beam5.65x heavierlighter
Strong panel or plate3.25x 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, Aluminum 3003-O or DMLS Ti-6Al-4V ELI Titanium?

Aluminum 3003-O stretches further before it breaks: 30% elongation at break against 8.7% for DMLS Ti-6Al-4V ELI Titanium.

Thermal

Which conducts heat better, Aluminum 3003-O or DMLS Ti-6Al-4V ELI Titanium?

Aluminum 3003-O conducts heat better: 193 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 23.2 µm/m·K for Aluminum 3003-O.
