C11000 ETP copper, annealed to 0.050 mm grain size (OS050), 1 in. rod, copper.org typical values
ASTM A992 W-shapes; Fy/Fu specified minimums from AISC publications (AISC 360-16 Commentary; Modern Steel Construction); elastic constants AISC 360; physical constants from the bauforumstahl structural-steel EPD, which names A992 among covered product standards.
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions
Is Copper C110 stronger than Steel A992?
Steel A992 is stronger: its yield strength is 385 MPa against 69 MPa for Copper C110 (5.58x).
Which is lighter, Copper C110 or Steel A992?
Steel A992 is lighter: 7,850 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Steel A992?
Steel A992 is stiffer: Young's modulus 200 GPa against 117 GPa for Copper C110, so the same part in Steel A992 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Steel A992?
For the same stiffness or strength: Steel A992 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.

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, Copper C110 or Steel A992?
Copper C110 conducts heat better: 391 W/m·K against 48 W/m·K for Steel A992.
Which expands less with temperature?
Steel A992 expands less: 12 µm/m·K against 16.9 µm/m·K for Copper C110.
