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.
SLS PA12 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Brass C260 stronger than SLS PA12 Nylon?
Brass C260 is stronger: its yield strength is 345 MPa against tensile strength 48 MPa for SLS PA12 Nylon (7.19x).
Which is lighter, Brass C260 or SLS PA12 Nylon?
SLS PA12 Nylon is lighter: 930 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or SLS PA12 Nylon?
Brass C260 is stiffer: Young's modulus 110 GPa against 1.65 GPa for SLS PA12 Nylon, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Brass C260 or SLS PA12 Nylon?
For the same stiffness or strength: Brass C260 is lighter for a stiff rod or tie (tension); SLS PA12 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 | SLS PA12 Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 7.29x heavier |
| Stiff beam (bending) | 12% heavier | lighter |
| Stiff panel or plate | 2.26x heavier | lighter |
| Strong rod or tie | 28% heavier | lighter |
| Strong beam | 2.46x heavier | lighter |
| Strong panel or plate | 3.42x 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).
