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.
SLS PA12 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is Copper C12200 stronger than SLS PA12 Nylon?
Copper C12200 is stronger: its yield strength is 69 MPa against tensile strength 48 MPa for SLS PA12 Nylon (44%).
Which is lighter, Copper C12200 or SLS PA12 Nylon?
SLS PA12 Nylon is lighter: 930 kg/m³ against 8,941 kg/m³ for Copper C12200.
Which is stiffer, Copper C12200 or SLS PA12 Nylon?
Copper C12200 is stiffer: Young's modulus 117 GPa against 1.65 GPa for SLS PA12 Nylon, so the same part in Copper C12200 deflects less under the same load.
Which is lighter for the same job, Copper C12200 or SLS PA12 Nylon?
For the same stiffness or strength: Copper C12200 is lighter for a stiff rod or tie (tension); SLS PA12 Nylon 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).
Which is more ductile, Copper C12200 or SLS PA12 Nylon?
Copper C12200 stretches further before it breaks: 45% elongation at break against 18% for SLS PA12 Nylon.
