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 7075-T6 stronger than Zinc Zamak 3? Aluminum 7075-T6 is stronger: its yield strength is 503 MPa against 221 MPa for Zinc Zamak 3 (2.28x).
Which is lighter, Aluminum 7075-T6 or Zinc Zamak 3? Aluminum 7075-T6 is lighter: 2,800 kg/m³ against 6,600 kg/m³ for Zinc Zamak 3.
Which is stiffer, Aluminum 7075-T6 or Zinc Zamak 3? Zinc Zamak 3 is stiffer: Young's modulus 85.5 GPa against 71 GPa for Aluminum 7075-T6, so the same part in Zinc Zamak 3 deflects less under the same load.
Which is lighter for the same job, Aluminum 7075-T6 or Zinc Zamak 3? For the same stiffness or strength: Aluminum 7075-T6 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 7075-T6 Zinc Zamak 3 Stiff rod or tie (tension) lighter 1.96x heavier Stiff beam (bending) lighter 2.15x heavier Stiff panel or plate lighter 2.22x heavier Strong rod or tie lighter 5.36x heavier Strong beam lighter 4.08x heavier Strong panel or plate lighter 3.56x 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).
Thermal Which conducts heat better, Aluminum 7075-T6 or Zinc Zamak 3? Aluminum 7075-T6 conducts heat better: 130 W/m·K against 113 W/m·K for Zinc Zamak 3.
Which expands less with temperature? Aluminum 7075-T6 expands less: 23.4 µm/m·K against 27.4 µm/m·K for Zinc Zamak 3.
