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.
FDM ASA is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is Aluminum 3003-O stronger than FDM ASA?
Aluminum 3003-O is stronger: its yield strength is 40 MPa against tensile strength 37 MPa for FDM ASA (8%).
Which is lighter, Aluminum 3003-O or FDM ASA?
FDM ASA is lighter: 1,050 kg/m³ against 2,730 kg/m³ for Aluminum 3003-O.
Which is stiffer, Aluminum 3003-O or FDM ASA?
Aluminum 3003-O is stiffer: Young's modulus 69 GPa against 2.45 GPa for FDM ASA, so the same part in Aluminum 3003-O deflects less under the same load.
Which is lighter for the same job, Aluminum 3003-O or FDM ASA?
For the same stiffness or strength: Aluminum 3003-O is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; FDM ASA is lighter for a 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, Aluminum 3003-O or FDM ASA?
Aluminum 3003-O stretches further before it breaks: 30% elongation at break against 9.2% for FDM ASA.
Thermal
Which conducts heat better, Aluminum 3003-O or FDM ASA?
Aluminum 3003-O conducts heat better: 193 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature?
Aluminum 3003-O expands less: 23.2 µm/m·K against 95 µm/m·K for FDM ASA.
