Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Mechanical Is Copper C10100 stronger than Steel AISI 1045? Steel AISI 1045 is stronger: its yield strength is 531 MPa against 69 MPa for Copper C10100 (7.7x).
Which is lighter, Copper C10100 or Steel AISI 1045? Steel AISI 1045 is lighter: 7,800 kg/m³ against 8,941 kg/m³ for Copper C10100.
Which is stiffer, Copper C10100 or Steel AISI 1045? Steel AISI 1045 is stiffer: Young's modulus 210 GPa against 117 GPa for Copper C10100, so the same part in Steel AISI 1045 deflects less under the same load.
Which is lighter for the same job, Copper C10100 or Steel AISI 1045? For the same stiffness or strength: Steel AISI 1045 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Copper C10100 Steel AISI 1045 Stiff rod or tie (tension) 2.05x heavier lighter Stiff beam (bending) 1.53x heavier lighter Stiff panel or plate 39% heavier lighter Strong rod or tie 8.82x heavier lighter Strong beam 4.47x heavier lighter Strong panel or plate 3.18x 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 is more ductile, Copper C10100 or Steel AISI 1045? Copper C10100 stretches further before it breaks: 45% elongation at break against 12% for Steel AISI 1045.
Thermal Which conducts heat better, Copper C10100 or Steel AISI 1045? Copper C10100 conducts heat better: 391 W/m·K against 42.5 W/m·K for Steel AISI 1045.
Which expands less with temperature? Steel AISI 1045 expands less: 12 µm/m·K against 16.9 µm/m·K for Copper C10100.
