Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Is Rubber stronger than Zinc Zamak 3? Zinc Zamak 3 is stronger: its yield strength is 221 MPa against tensile strength 23 MPa for Rubber (9.61x).
Which is lighter, Rubber or Zinc Zamak 3? Rubber is lighter: 960 kg/m³ against 6,600 kg/m³ for Zinc Zamak 3.
Which is lighter for the same job, Rubber or Zinc Zamak 3? For the same stiffness or strength: Rubber is lighter for a strong beam, strong panel or plate; Zinc Zamak 3 is lighter for a strong rod or tie.
Part that must be Rubber Zinc Zamak 3 Strong rod or tie 40% heavier lighter Strong beam lighter 1.52x heavier Strong panel or plate lighter 2.22x 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 conducts heat better, Rubber or Zinc Zamak 3? Zinc Zamak 3 conducts heat better: 113 W/m·K against 0.151 W/m·K for Rubber.
