Questions
Is Brass C360 stronger than Glass?
Brass C360 is stronger: its yield strength is 310 MPa against tensile strength 41 MPa for Glass (7.56x).
Which is lighter, Brass C360 or Glass?
Glass is lighter: 2,500 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or Glass?
Brass C360 is stiffer: Young's modulus 96.5 GPa against 72 GPa for Glass, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Brass C360 or Glass?
For the same stiffness or strength: Brass C360 is lighter for a strong rod or tie, strong beam; Glass is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong panel or plate.
| Part that must be | Brass C360 | Glass |
|---|---|---|
| Stiff rod or tie (tension) | 2.54x heavier | lighter |
| Stiff beam (bending) | 2.94x heavier | lighter |
| Stiff panel or plate | 3.08x heavier | lighter |
| Strong rod or tie | lighter | 2.22x heavier |
| Strong beam | lighter | 13% heavier |
| Strong panel or plate | 24% 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 C360 or Glass?
Brass C360 conducts heat better: 116 W/m·K against 0.937 W/m·K for Glass.
Which expands less with temperature?
Glass expands less: 8.3 µm/m·K against 20.5 µm/m·K for Brass C360.
