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 2024-T351 stronger than Wood? Aluminum 2024-T351 is stronger: its yield strength is 324 MPa against tensile strength 99 MPa for Wood (3.27x).
Which is stiffer, Aluminum 2024-T351 or Wood? Aluminum 2024-T351 is stiffer: Young's modulus 73.1 GPa against 12.5 GPa for Wood, so the same part in Aluminum 2024-T351 deflects less under the same load.
Which conducts heat better, Aluminum 2024-T351 or Wood? Aluminum 2024-T351 conducts heat better: 120 W/m·K against 0.18 W/m·K for Wood.
Which expands less with temperature? Wood expands less: 3.8 µm/m·K against 22.9 µm/m·K for Aluminum 2024-T351.
