Questions
Is Copper C110 stronger than Plastic Polypropylene?
Copper C110 is stronger: its yield strength is 69 MPa against 33 MPa for Plastic Polypropylene (2.09x).
Which is lighter, Copper C110 or Plastic Polypropylene?
Plastic Polypropylene is lighter: 900 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Plastic Polypropylene?
Copper C110 is stiffer: Young's modulus 117 GPa against 1.45 GPa for Plastic Polypropylene, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Plastic Polypropylene?
For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension); Plastic Polypropylene is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Copper C110 | Plastic Polypropylene |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 8.16x heavier |
| Stiff beam (bending) | 10% heavier | lighter |
| Stiff panel or plate | 2.29x heavier | lighter |
| Strong rod or tie | 4.74x heavier | lighter |
| Strong beam | 6.06x heavier | lighter |
| Strong panel or plate | 6.85x 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 conducts heat better, Copper C110 or Plastic Polypropylene?
Copper C110 conducts heat better: 391 W/m·K against 0.195 W/m·K for Plastic Polypropylene.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 90 µm/m·K for Plastic Polypropylene.
