Questions

Is Copper C110 stronger than Rubber?

Copper C110 is stronger: its yield strength is 69 MPa against tensile strength 23 MPa for Rubber (3x).

Which is lighter, Copper C110 or Rubber?

Rubber is lighter: 960 kg/m³ against 8,913 kg/m³ for Copper C110.

Which is lighter for the same job, Copper C110 or Rubber?

For the same stiffness or strength: Rubber is lighter for a strong rod or tie, strong beam, strong panel or plate.

Part that must beCopper C110Rubber
Strong rod or tie3.09x heavierlighter
Strong beam4.46x heavierlighter
Strong panel or plate5.36x 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 conducts heat better, Copper C110 or Rubber?

Copper C110 conducts heat better: 391 W/m·K against 0.151 W/m·K for Rubber.
