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 4340? Steel AISI 4340 is stronger: its yield strength is 1,035 MPa against 69 MPa for Copper C10100 (15x).
Which is lighter, Copper C10100 or Steel AISI 4340? Steel AISI 4340 is lighter: 7,840 kg/m³ against 8,941 kg/m³ for Copper C10100.
Which is stiffer, Copper C10100 or Steel AISI 4340? Steel AISI 4340 is stiffer: Young's modulus 200 GPa against 117 GPa for Copper C10100, so the same part in Steel AISI 4340 deflects less under the same load.
Which is lighter for the same job, Copper C10100 or Steel AISI 4340? For the same stiffness or strength: Steel AISI 4340 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 4340 Stiff rod or tie (tension) 1.95x heavier lighter Stiff beam (bending) 49% heavier lighter Stiff panel or plate 36% heavier lighter Strong rod or tie 17.1x heavier lighter Strong beam 6.94x heavier lighter Strong panel or plate 4.42x 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 4340? Copper C10100 stretches further before it breaks: 45% elongation at break against 18% for Steel AISI 4340.
Thermal Which conducts heat better, Copper C10100 or Steel AISI 4340? Copper C10100 conducts heat better: 391 W/m·K against 37.5 W/m·K for Steel AISI 4340.
Which expands less with temperature? Steel AISI 4340 expands less: 11.3 µm/m·K against 16.9 µm/m·K for Copper C10100.
