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 C110 stronger than Copper C12200?
Copper C110 is stronger: its yield strength is 69 MPa against 69 MPa for Copper C12200 (0%).
Which is lighter, Copper C110 or Copper C12200?
Copper C110 is lighter: 8,913 kg/m³ against 8,941 kg/m³ for Copper C12200.
Which is stiffer, Copper C110 or Copper C12200?
Copper C110 is stiffer: Young's modulus 117 GPa against 117 GPa for Copper C12200, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Copper C12200?
For the same stiffness or strength they weigh about the same.

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 C110 or Copper C12200?
Copper C110 stretches further before it breaks: 55% elongation at break against 45% for Copper C12200.
Thermal
Which conducts heat better, Copper C110 or Copper C12200?
Copper C110 conducts heat better: 391 W/m·K against 339 W/m·K for Copper C12200.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 16.9 µm/m·K for Copper C12200.
