Questions

Mechanical

Is Aluminum 5052-H32 stronger than Zinc Zamak 3?

Zinc Zamak 3 is stronger: its yield strength is 221 MPa against 195 MPa for Aluminum 5052-H32 (13%).

Which is lighter, Aluminum 5052-H32 or Zinc Zamak 3?

Aluminum 5052-H32 is lighter: 2,685 kg/m³ against 6,600 kg/m³ for Zinc Zamak 3.

Which is stiffer, Aluminum 5052-H32 or Zinc Zamak 3?

Zinc Zamak 3 is stiffer: Young's modulus 85.5 GPa against 70 GPa for Aluminum 5052-H32, so the same part in Zinc Zamak 3 deflects less under the same load.

Which is lighter for the same job, Aluminum 5052-H32 or Zinc Zamak 3?

For the same stiffness or strength: Aluminum 5052-H32 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 beAluminum 5052-H32Zinc Zamak 3
Stiff rod or tie (tension)lighter2.01x heavier
Stiff beam (bending)lighter2.22x heavier
Stiff panel or platelighter2.3x heavier
Strong rod or tielighter2.17x heavier
Strong beamlighter2.26x heavier
Strong panel or platelighter2.31x 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 5052-H32 or Zinc Zamak 3?

Aluminum 5052-H32 stretches further before it breaks: 12% elongation at break against 10% for Zinc Zamak 3.
