Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Mechanical Is Aluminum A380 stronger than Zinc Zamak 3? Zinc Zamak 3 is stronger: its yield strength is 221 MPa against 160 MPa for Aluminum A380 (38%).
Which is lighter, Aluminum A380 or Zinc Zamak 3? Aluminum A380 is lighter: 2,713 kg/m³ against 6,600 kg/m³ for Zinc Zamak 3.
Which is stiffer, Aluminum A380 or Zinc Zamak 3? Zinc Zamak 3 is stiffer: Young's modulus 85.5 GPa against 71 GPa for Aluminum A380, so the same part in Zinc Zamak 3 deflects less under the same load.
Which is lighter for the same job, Aluminum A380 or Zinc Zamak 3? For the same stiffness or strength: Aluminum A380 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Aluminum A380 Zinc Zamak 3 Stiff rod or tie (tension) lighter 2.02x heavier Stiff beam (bending) lighter 2.22x heavier Stiff panel or plate lighter 2.29x heavier Strong rod or tie lighter 1.76x heavier Strong beam lighter 1.96x heavier Strong panel or plate lighter 2.07x heavier
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 is more ductile, Aluminum A380 or Zinc Zamak 3? Zinc Zamak 3 stretches further before it breaks: 10% elongation at break against 3.5% for Aluminum A380.
Thermal Which conducts heat better, Aluminum A380 or Zinc Zamak 3? Zinc Zamak 3 conducts heat better: 113 W/m·K against 96.2 W/m·K for Aluminum A380.
Which expands less with temperature? Aluminum A380 expands less: 21.8 µm/m·K against 27.4 µm/m·K for Zinc Zamak 3.
