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 Drywall stronger than Magnesium AZ91D? Magnesium AZ91D is stronger: its yield strength is 150 MPa against tensile strength 1.5 MPa for Drywall (100x).
Which is stiffer, Drywall or Magnesium AZ91D? Magnesium AZ91D is stiffer: Young's modulus 45 GPa against 1.5 GPa for Drywall, so the same part in Magnesium AZ91D deflects less under the same load.
Which expands less with temperature? Drywall expands less: 16.7 µm/m·K against 25 µm/m·K for Magnesium AZ91D.
