Questions
Is Copper C110 stronger than Plastic Nylon PA66?
Plastic Nylon PA66 is stronger: its yield strength is 85 MPa against 69 MPa for Copper C110 (23%).
Which is lighter, Copper C110 or Plastic Nylon PA66?
Plastic Nylon PA66 is lighter: 1,130 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Plastic Nylon PA66?
Copper C110 is stiffer: Young's modulus 117 GPa against 3 GPa for Plastic Nylon PA66, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Plastic Nylon PA66?
For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension); Plastic Nylon PA66 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 Nylon PA66 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 4.95x heavier |
| Stiff beam (bending) | 26% heavier | lighter |
| Stiff panel or plate | 2.32x heavier | lighter |
| Strong rod or tie | 9.72x heavier | lighter |
| Strong beam | 9.06x heavier | lighter |
| Strong panel or plate | 8.75x 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 Nylon PA66?
Copper C110 conducts heat better: 391 W/m·K against 0.33 W/m·K for Plastic Nylon PA66.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 98 µm/m·K for Plastic Nylon PA66.
