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 Aluminum 6061-T6 stronger than Aluminum?
Aluminum 6061-T6 is stronger: its yield strength is 276 MPa against 276 MPa for Aluminum (0%).
Which is lighter, Aluminum 6061-T6 or Aluminum?
Aluminum 6061-T6 is lighter: 2,700 kg/m³ against 2,700 kg/m³ for Aluminum.
Which is stiffer, Aluminum 6061-T6 or Aluminum?
Aluminum 6061-T6 is stiffer: Young's modulus 68.3 GPa against 68.3 GPa for Aluminum, so the same part in Aluminum 6061-T6 deflects less under the same load.
Which is lighter for the same job, Aluminum 6061-T6 or Aluminum?
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 conducts heat better, Aluminum 6061-T6 or Aluminum?
Aluminum 6061-T6 conducts heat better: 167 W/m·K against 167 W/m·K for Aluminum.
Which expands less with temperature?
Aluminum 6061-T6 expands less: 23.6 µm/m·K against 23.6 µm/m·K for Aluminum.
