Questions
Is Brass C260 stronger than Glass?
Brass C260 is stronger: its yield strength is 345 MPa against tensile strength 41 MPa for Glass (8.41x).
Which is lighter, Brass C260 or Glass?
Glass is lighter: 2,500 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Glass?
Brass C260 is stiffer: Young's modulus 110 GPa against 72 GPa for Glass, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Brass C260 or Glass?
For the same stiffness or strength: Brass C260 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 C260 | Glass |
|---|---|---|
| Stiff rod or tie (tension) | 2.23x heavier | lighter |
| Stiff beam (bending) | 2.76x heavier | lighter |
| Stiff panel or plate | 2.96x heavier | lighter |
| Strong rod or tie | lighter | 2.47x heavier |
| Strong beam | lighter | 21% heavier |
| Strong panel or plate | 18% 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 Glass?
Brass C260 conducts heat better: 121 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 µm/m·K for Brass C260.
