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 stronger than Aluminum 6061-T6?
Aluminum is stronger: its yield strength is 276 MPa against 276 MPa for Aluminum 6061-T6 (0%).
Which is lighter, Aluminum or Aluminum 6061-T6?
Aluminum is lighter: 2,700 kg/m³ against 2,700 kg/m³ for Aluminum 6061-T6.
Which is stiffer, Aluminum or Aluminum 6061-T6?
Aluminum is stiffer: Young's modulus 68.3 GPa against 68.3 GPa for Aluminum 6061-T6, so the same part in Aluminum deflects less under the same load.
Which is lighter for the same job, Aluminum or Aluminum 6061-T6?
For the same stiffness or strength they weigh about the same.

Aluminum conducts heat better: 167 W/m·K against 167 W/m·K for Aluminum 6061-T6.
Which expands less with temperature?
Aluminum expands less: 23.6 µm/m·K against 23.6 µm/m·K for Aluminum 6061-T6.
