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 Ceramic Alumina 96%? Aluminum 6061-T6 is stronger: its yield strength is 276 MPa against tensile strength 221 MPa for Ceramic Alumina 96% (25%).
Which is lighter, Aluminum 6061-T6 or Ceramic Alumina 96%? Aluminum 6061-T6 is lighter: 2,700 kg/m³ against 3,720 kg/m³ for Ceramic Alumina 96%.
Which is stiffer, Aluminum 6061-T6 or Ceramic Alumina 96%? Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 68.3 GPa for Aluminum 6061-T6, so the same part in Ceramic Alumina 96% deflects less under the same load.
Which is lighter for the same job, Aluminum 6061-T6 or Ceramic Alumina 96%? For the same stiffness or strength: Aluminum 6061-T6 is lighter for a strong rod or tie, strong beam, strong panel or plate; Ceramic Alumina 96% is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate.
Part that must be Aluminum 6061-T6 Ceramic Alumina 96% Stiff rod or tie (tension) 3.22x heavier lighter Stiff beam (bending) 1.53x heavier lighter Stiff panel or plate 19% heavier lighter Strong rod or tie lighter 1.72x heavier Strong beam lighter 1.6x heavier Strong panel or plate lighter 1.54x heavier
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 Ceramic Alumina 96%? Aluminum 6061-T6 conducts heat better: 167 W/m·K against 24.7 W/m·K for Ceramic Alumina 96%.
Which expands less with temperature? Ceramic Alumina 96% expands less: 8.2 µm/m·K against 23.6 µm/m·K for Aluminum 6061-T6.
