Questions Is Aluminum A380 stronger than Magnesium AZ31B-H24? Magnesium AZ31B-H24 is stronger: its yield strength is 220 MPa against 160 MPa for Aluminum A380 (38%).
Which is lighter, Aluminum A380 or Magnesium AZ31B-H24? Magnesium AZ31B-H24 is lighter: 1,769 kg/m³ against 2,713 kg/m³ for Aluminum A380.
Which is stiffer, Aluminum A380 or Magnesium AZ31B-H24? Aluminum A380 is stiffer: Young's modulus 71 GPa against 44.8 GPa for Magnesium AZ31B-H24, so the same part in Aluminum A380 deflects less under the same load.
Which is lighter for the same job, Aluminum A380 or Magnesium AZ31B-H24? For the same stiffness or strength: Aluminum A380 is lighter for a stiff rod or tie (tension); Magnesium AZ31B-H24 is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Aluminum A380 Magnesium AZ31B-H24 Stiff rod or tie (tension) lighter 3% heavier Stiff beam (bending) 22% heavier lighter Stiff panel or plate 32% heavier lighter Strong rod or tie 2.11x heavier lighter Strong beam 1.9x heavier lighter Strong panel or plate 1.8x 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, Aluminum A380 or Magnesium AZ31B-H24? Aluminum A380 conducts heat better: 96.2 W/m·K against 76.9 W/m·K for Magnesium AZ31B-H24.
Which expands less with temperature? Aluminum A380 expands less: 21.8 µm/m·K against 26.8 µm/m·K for Magnesium AZ31B-H24.
