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 Aluminum 1100-O stronger than Plastic Nylon?
Plastic Nylon is stronger: its yield strength is 63.1 MPa against 35 MPa for Aluminum 1100-O (1.8x).
Which is lighter, Aluminum 1100-O or Plastic Nylon?
Plastic Nylon is lighter: 1,140 kg/m³ against 2,710 kg/m³ for Aluminum 1100-O.
Which is stiffer, Aluminum 1100-O or Plastic Nylon?
Aluminum 1100-O is stiffer: Young's modulus 69 GPa against 2.33 GPa for Plastic Nylon, so the same part in Aluminum 1100-O deflects less under the same load.
Which is lighter for the same job, Aluminum 1100-O or Plastic Nylon?
For the same stiffness or strength: Aluminum 1100-O is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; Plastic Nylon is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Aluminum 1100-O | Plastic Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 12.5x heavier |
| Stiff beam (bending) | lighter | 2.29x heavier |
| Stiff panel or plate | lighter | 30% heavier |
| Strong rod or tie | 4.29x heavier | lighter |
| Strong beam | 3.52x heavier | lighter |
| Strong panel or plate | 3.19x 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, Aluminum 1100-O or Plastic Nylon?
Aluminum 1100-O conducts heat better: 222 W/m·K against 0.33 W/m·K for Plastic Nylon.
Which expands less with temperature?
Aluminum 1100-O expands less: 23.6 µm/m·K against 100 µm/m·K for Plastic Nylon.
