Questions Is Magnesium AZ91D stronger than Plywood? Magnesium AZ91D is stronger: its yield strength is 150 MPa against tensile strength 41.4 MPa for Plywood (3.63x).
Which is stiffer, Magnesium AZ91D or Plywood? Magnesium AZ91D is stiffer: Young's modulus 45 GPa against 7.45 GPa for Plywood, so the same part in Magnesium AZ91D deflects less under the same load.
Which conducts heat better, Magnesium AZ91D or Plywood? Magnesium AZ91D conducts heat better: 72 W/m·K against 0.12 W/m·K for Plywood.
Which expands less with temperature? Plywood expands less: 3.8 µm/m·K against 25 µm/m·K for Magnesium AZ91D.
