Questions

Mechanical

Is Copper C10100 stronger than Zinc Zamak 3?

Zinc Zamak 3 is stronger: its yield strength is 221 MPa against 69 MPa for Copper C10100 (3.2x).

Which is lighter, Copper C10100 or Zinc Zamak 3?

Zinc Zamak 3 is lighter: 6,600 kg/m³ against 8,941 kg/m³ for Copper C10100.

Which is stiffer, Copper C10100 or Zinc Zamak 3?

Copper C10100 is stiffer: Young's modulus 117 GPa against 85.5 GPa for Zinc Zamak 3, so the same part in Copper C10100 deflects less under the same load.

Which is lighter for the same job, Copper C10100 or Zinc Zamak 3?

For the same stiffness or strength: Copper C10100 is lighter for a stiff rod or tie (tension); Zinc Zamak 3 is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must beCopper C10100Zinc Zamak 3
Stiff rod or tie (tension)lighter1% heavier
Stiff beam (bending)16% heavierlighter
Stiff panel or plate22% heavierlighter
Strong rod or tie4.34x heavierlighter
Strong beam2.94x heavierlighter
Strong panel or plate2.42x heavierlighter

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, Copper C10100 or Zinc Zamak 3?

Copper C10100 stretches further before it breaks: 45% elongation at break against 10% for Zinc Zamak 3.

Thermal

Which conducts heat better, Copper C10100 or Zinc Zamak 3?

Copper C10100 conducts heat better: 391 W/m·K against 113 W/m·K for Zinc Zamak 3.

Which expands less with temperature?

Copper C10100 expands less: 16.9 µm/m·K against 27.4 µm/m·K for Zinc Zamak 3.
