Questions
Is Copper C110 stronger than Plastic UHMWPE?
Copper C110 is stronger: its yield strength is 69 MPa against 20 MPa for Plastic UHMWPE (3.45x).
Which is lighter, Copper C110 or Plastic UHMWPE?
Plastic UHMWPE is lighter: 930 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Plastic UHMWPE?
Copper C110 is stiffer: Young's modulus 117 GPa against 0.66 GPa for Plastic UHMWPE, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Plastic UHMWPE?
For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension), stiff beam (bending); Plastic UHMWPE is lighter for a stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Copper C110 | Plastic UHMWPE |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 18.5x heavier |
| Stiff beam (bending) | lighter | 39% heavier |
| Stiff panel or plate | 1.71x heavier | lighter |
| Strong rod or tie | 2.78x heavier | lighter |
| Strong beam | 4.2x heavier | lighter |
| Strong panel or plate | 5.16x 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 UHMWPE?
Copper C110 conducts heat better: 391 W/m·K against 0.4 W/m·K for Plastic UHMWPE.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 200 µm/m·K for Plastic UHMWPE.
