Questions
Is Brass C360 stronger than Copper C110?
Brass C360 is stronger: its yield strength is 310 MPa against 69 MPa for Copper C110 (4.49x).
Which is lighter, Brass C360 or Copper C110?
Brass C360 is lighter: 8,498 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Brass C360 or Copper C110?
Copper C110 is stiffer: Young's modulus 117 GPa against 96.5 GPa for Brass C360, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Brass C360 or Copper C110?
For the same stiffness or strength: Brass C360 is lighter for a strong rod or tie, strong beam, strong panel or plate; Copper C110 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate.
| Part that must be | Brass C360 | Copper C110 |
|---|---|---|
| Stiff rod or tie (tension) | 16% heavier | lighter |
| Stiff beam (bending) | 5% heavier | lighter |
| Stiff panel or plate | 2% heavier | lighter |
| Strong rod or tie | lighter | 4.71x heavier |
| Strong beam | lighter | 2.86x heavier |
| Strong panel or plate | lighter | 2.22x 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 is more ductile, Brass C360 or Copper C110?
Copper C110 stretches further before it breaks: 55% elongation at break against 25% for Brass C360.
Which conducts heat better, Brass C360 or Copper C110?
Copper C110 conducts heat better: 391 W/m·K against 116 W/m·K for Brass C360.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 20.5 µm/m·K for Brass C360.
