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.
Part that must be Aluminum Aluminum 6061-T6 Stiff rod or tie (tension) about equal about equal Stiff beam (bending) about equal about equal Stiff panel or plate about equal about equal Strong rod or tie about equal about equal Strong beam about equal about equal Strong panel or plate about equal about equal
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 or Aluminum 6061-T6? 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.
