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 C12200 stronger than Plastic Polypropylene?
Copper C12200 is stronger: its yield strength is 69 MPa against 33 MPa for Plastic Polypropylene (2.09x).
Which is lighter, Copper C12200 or Plastic Polypropylene?
Plastic Polypropylene is lighter: 900 kg/m³ against 8,941 kg/m³ for Copper C12200.
Which is stiffer, Copper C12200 or Plastic Polypropylene?
Copper C12200 is stiffer: Young's modulus 117 GPa against 1.45 GPa for Plastic Polypropylene, so the same part in Copper C12200 deflects less under the same load.
Which is lighter for the same job, Copper C12200 or Plastic Polypropylene?
For the same stiffness or strength: Copper C12200 is lighter for a stiff rod or tie (tension); Plastic Polypropylene is lighter for a 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).
Thermal
Which conducts heat better, Copper C12200 or Plastic Polypropylene?
Copper C12200 conducts heat better: 339 W/m·K against 0.195 W/m·K for Plastic Polypropylene.
Which expands less with temperature?
Copper C12200 expands less: 16.9 µm/m·K against 90 µm/m·K for Plastic Polypropylene.
