Questions Is Steel AISI 1045 stronger than Titanium? Titanium is stronger: its yield strength is 885 MPa against 531 MPa for Steel AISI 1045 (1.67x).
Which is lighter, Steel AISI 1045 or Titanium? Titanium is lighter: 4,430 kg/m³ against 7,800 kg/m³ for Steel AISI 1045.
Which is stiffer, Steel AISI 1045 or Titanium? Steel AISI 1045 is stiffer: Young's modulus 210 GPa against 115 GPa for Titanium, so the same part in Steel AISI 1045 deflects less under the same load.
Which is lighter for the same job, Steel AISI 1045 or Titanium? For the same stiffness or strength: Steel AISI 1045 is lighter for a stiff rod or tie (tension); Titanium is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Steel AISI 1045 Titanium Stiff rod or tie (tension) lighter 4% heavier Stiff beam (bending) 30% heavier lighter Stiff panel or plate 44% heavier lighter Strong rod or tie 2.93x heavier lighter Strong beam 2.48x heavier lighter Strong panel or plate 2.27x 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, Steel AISI 1045 or Titanium? Steel AISI 1045 conducts heat better: 42.5 W/m·K against 6.6 W/m·K for Titanium.
Which expands less with temperature? Titanium expands less: 9 µm/m·K against 12 µm/m·K for Steel AISI 1045.
