Questions Is Rubber stronger than Titanium? Titanium is stronger: its yield strength is 885 MPa against tensile strength 23 MPa for Rubber (38.5x).
Which is lighter, Rubber or Titanium? Rubber is lighter: 960 kg/m³ against 4,430 kg/m³ for Titanium.
Which is lighter for the same job, Rubber or Titanium? For the same stiffness or strength: Titanium is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Rubber Titanium Strong rod or tie 8.34x heavier lighter Strong beam 2.47x heavier lighter Strong panel or plate 34% 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, Rubber or Titanium? Titanium conducts heat better: 6.6 W/m·K against 0.151 W/m·K for Rubber.
