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.
FDM PAHT-CF is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Brass C360 stronger than FDM PAHT-CF?
Brass C360 is stronger: its yield strength is 310 MPa against tensile strength 92 MPa for FDM PAHT-CF (3.37x).
Which is lighter, Brass C360 or FDM PAHT-CF?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or FDM PAHT-CF?
Brass C360 is stiffer: Young's modulus 96.5 GPa against 3.86 GPa for FDM PAHT-CF, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Brass C360 or FDM PAHT-CF?
For the same stiffness or strength: Brass C360 is lighter for a stiff rod or tie (tension); FDM PAHT-CF 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 C360 | FDM PAHT-CF |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 3.12x heavier |
| Stiff beam (bending) | 1.6x heavier | lighter |
| Stiff panel or plate | 2.74x heavier | lighter |
| Strong rod or tie | 2.38x heavier | lighter |
| Strong beam | 3.57x heavier | lighter |
| Strong panel or plate | 4.37x 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).
