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 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Brass C260 stronger than Plastic Nylon?
Brass C260 is stronger: its yield strength is 345 MPa against 63.1 MPa for Plastic Nylon (5.47x).
Which is lighter, Brass C260 or Plastic Nylon?
Plastic Nylon is lighter: 1,140 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Plastic Nylon?
Brass C260 is stiffer: Young's modulus 110 GPa against 2.33 GPa for Plastic Nylon, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Brass C260 or Plastic Nylon?
For the same stiffness or strength: Brass C260 is lighter for a stiff rod or tie (tension); Plastic Nylon 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 | Brass C260 | Plastic Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 6.33x heavier |
| Stiff beam (bending) | 9% heavier | lighter |
| Stiff panel or plate | 2.07x heavier | lighter |
| Strong rod or tie | 37% heavier | lighter |
| Strong beam | 2.41x heavier | lighter |
| Strong panel or plate | 3.2x 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, Brass C260 or Plastic Nylon?
Brass C260 conducts heat better: 121 W/m·K against 0.33 W/m·K for Plastic Nylon.
Which expands less with temperature?
Brass C260 expands less: 20 µm/m·K against 100 µm/m·K for Plastic Nylon.
