Questions
Is Copper C110 stronger than Plastic ABS (bulk/injection)?
Copper C110 is stronger: its yield strength is 69 MPa against 45 MPa for Plastic ABS (bulk/injection) (1.53x).
Which is lighter, Copper C110 or Plastic ABS (bulk/injection)?
Plastic ABS (bulk/injection) is lighter: 1,040 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Plastic ABS (bulk/injection)?
Copper C110 is stiffer: Young's modulus 117 GPa against 2.3 GPa for Plastic ABS (bulk/injection), so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Plastic ABS (bulk/injection)?
For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension); Plastic ABS (bulk/injection) 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 ABS (bulk/injection) |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 5.95x heavier |
| Stiff beam (bending) | 20% heavier | lighter |
| Stiff panel or plate | 2.31x heavier | lighter |
| Strong rod or tie | 5.59x heavier | lighter |
| Strong beam | 6.45x heavier | lighter |
| Strong panel or plate | 6.92x 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 ABS (bulk/injection)?
Copper C110 conducts heat better: 391 W/m·K against 0.17 W/m·K for Plastic ABS (bulk/injection).
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 95 µm/m·K for Plastic ABS (bulk/injection).
