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 6061-T6 stronger than Zinc Zamak 3? Aluminum 6061-T6 is stronger: its yield strength is 276 MPa against 221 MPa for Zinc Zamak 3 (25%).
Which is lighter, Aluminum 6061-T6 or Zinc Zamak 3? Aluminum 6061-T6 is lighter: 2,700 kg/m³ against 6,600 kg/m³ for Zinc Zamak 3.
Which is stiffer, Aluminum 6061-T6 or Zinc Zamak 3? Zinc Zamak 3 is stiffer: Young's modulus 85.5 GPa against 68.3 GPa for Aluminum 6061-T6, so the same part in Zinc Zamak 3 deflects less under the same load.
Which is lighter for the same job, Aluminum 6061-T6 or Zinc Zamak 3? For the same stiffness or strength: Aluminum 6061-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 6061-T6 Zinc Zamak 3 Stiff rod or tie (tension) lighter 1.95x heavier Stiff beam (bending) lighter 2.18x heavier Stiff panel or plate lighter 2.27x heavier Strong rod or tie lighter 3.05x heavier Strong beam lighter 2.83x heavier Strong panel or plate lighter 2.73x 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 6061-T6 or Zinc Zamak 3? Aluminum 6061-T6 stretches further before it breaks: 17% elongation at break against 10% for Zinc Zamak 3.
Thermal Which conducts heat better, Aluminum 6061-T6 or Zinc Zamak 3? Aluminum 6061-T6 conducts heat better: 167 W/m·K against 113 W/m·K for Zinc Zamak 3.
Which expands less with temperature? Aluminum 6061-T6 expands less: 23.6 µm/m·K against 27.4 µm/m·K for Zinc Zamak 3.
