Questions Is Ceramic Alumina 96% stronger than Magnesium AZ91D? Ceramic Alumina 96% is stronger: its tensile strength is 221 MPa against yield strength 150 MPa for Magnesium AZ91D (47%).
Which is lighter, Ceramic Alumina 96% or Magnesium AZ91D? Magnesium AZ91D is lighter: 1,810 kg/m³ against 3,720 kg/m³ for Ceramic Alumina 96%.
Which is stiffer, Ceramic Alumina 96% or Magnesium AZ91D? Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 45 GPa for Magnesium AZ91D, so the same part in Ceramic Alumina 96% deflects less under the same load.
Which is lighter for the same job, Ceramic Alumina 96% or Magnesium AZ91D? For the same stiffness or strength: Ceramic Alumina 96% is lighter for a stiff rod or tie (tension), stiff beam (bending); Magnesium AZ91D is lighter for a stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Ceramic Alumina 96% Magnesium AZ91D Stiff rod or tie (tension) lighter 3.28x heavier Stiff beam (bending) lighter 26% heavier Stiff panel or plate 9% heavier lighter Strong rod or tie 39% heavier lighter Strong beam 1.59x heavier lighter Strong panel or plate 1.69x heavier lighter
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, Ceramic Alumina 96% or Magnesium AZ91D? Magnesium AZ91D conducts heat better: 72 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 25 µm/m·K for Magnesium AZ91D.
