Questions
Is Brass C260 stronger than Brass C360?
Brass C260 is stronger: its yield strength is 345 MPa against 310 MPa for Brass C360 (11%).
Which is lighter, Brass C260 or Brass C360?
Brass C360 is lighter: 8,498 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Brass C360?
Brass C260 is stiffer: Young's modulus 110 GPa against 96.5 GPa for Brass C360, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Brass C260 or Brass C360?
For the same stiffness or strength: Brass C260 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brass C260 | Brass C360 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 14% heavier |
| Stiff beam (bending) | lighter | 7% heavier |
| Stiff panel or plate | lighter | 4% heavier |
| Strong rod or tie | lighter | 11% heavier |
| Strong beam | lighter | 7% heavier |
| Strong panel or plate | lighter | 5% heavier |
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 Brass C360?
Brass C260 conducts heat better: 121 W/m·K against 116 W/m·K for Brass C360.
Which expands less with temperature?
Brass C260 expands less: 20 µm/m·K against 20.5 µm/m·K for Brass C360.
