Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Plastic TPU is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Copper C110 stronger than Plastic TPU?
Copper C110 is stronger: its yield strength is 69 MPa against tensile strength 23.7 MPa for Plastic TPU (2.91x).
Which is lighter, Copper C110 or Plastic TPU?
Plastic TPU is lighter: 1,220 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or Plastic TPU?
Copper C110 is stiffer: Young's modulus 117 GPa against 0.067 GPa for Plastic TPU, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or Plastic TPU?
For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; Plastic TPU is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Copper C110 | Plastic TPU |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 239x heavier |
| Stiff beam (bending) | lighter | 5.72x heavier |
| Stiff panel or plate | lighter | 1.65x heavier |
| Strong rod or tie | 2.51x heavier | lighter |
| Strong beam | 3.58x heavier | lighter |
| Strong panel or plate | 4.28x 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).
