Questions Is Plastic PBT GF30 stronger than Titanium? Titanium is stronger: its yield strength is 885 MPa against tensile strength 140 MPa for Plastic PBT GF30 (6.32x).
Which is lighter, Plastic PBT GF30 or Titanium? Plastic PBT GF30 is lighter: 1,530 kg/m³ against 4,430 kg/m³ for Titanium.
Which is stiffer, Plastic PBT GF30 or Titanium? Titanium is stiffer: Young's modulus 115 GPa against 9.8 GPa for Plastic PBT GF30, so the same part in Titanium deflects less under the same load.
Which is lighter for the same job, Plastic PBT GF30 or Titanium? For the same stiffness or strength: Plastic PBT GF30 is lighter for a stiff panel or plate, strong panel or plate; Titanium is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam.
Part that must be Plastic PBT GF30 Titanium Stiff rod or tie (tension) 4.04x heavier lighter Stiff beam (bending) 18% heavier lighter Stiff panel or plate lighter 28% heavier Strong rod or tie 2.18x heavier lighter Strong beam 18% heavier lighter Strong panel or plate lighter 15% 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 conducts heat better, Plastic PBT GF30 or Titanium? Titanium conducts heat better: 6.6 W/m·K against 0.27 W/m·K for Plastic PBT GF30.
Which expands less with temperature? Titanium expands less: 9 µm/m·K against 25 µm/m·K for Plastic PBT GF30.
