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 Brass C360 stronger than Zinc Zamak 3? Brass C360 is stronger: its yield strength is 310 MPa against 221 MPa for Zinc Zamak 3 (40%).
Which is lighter, Brass C360 or Zinc Zamak 3? Zinc Zamak 3 is lighter: 6,600 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or Zinc Zamak 3? Brass C360 is stiffer: Young's modulus 96.5 GPa against 85.5 GPa for Zinc Zamak 3, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Brass C360 or Zinc Zamak 3? For the same stiffness or strength: Brass C360 is lighter for a strong rod or tie; Zinc Zamak 3 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong beam, strong panel or plate.
Part that must be Brass C360 Zinc Zamak 3 Stiff rod or tie (tension) 14% heavier lighter Stiff beam (bending) 21% heavier lighter Stiff panel or plate 24% heavier lighter Strong rod or tie lighter 9% heavier Strong beam 3% heavier lighter Strong panel or plate 9% 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 is more ductile, Brass C360 or Zinc Zamak 3? Brass C360 stretches further before it breaks: 25% elongation at break against 10% for Zinc Zamak 3.
Thermal Which conducts heat better, Brass C360 or Zinc Zamak 3? Brass C360 conducts heat better: 116 W/m·K against 113 W/m·K for Zinc Zamak 3.
Which expands less with temperature? Brass C360 expands less: 20.5 µm/m·K against 27.4 µm/m·K for Zinc Zamak 3.
