Questions

Mechanical

Is Brass C260 stronger than Copper C12200?

Brass C260 is stronger: its yield strength is 345 MPa against 69 MPa for Copper C12200 (5x).

Which is lighter, Brass C260 or Copper C12200?

Brass C260 is lighter: 8,525 kg/m³ against 8,941 kg/m³ for Copper C12200.

Which is stiffer, Brass C260 or Copper C12200?

Copper C12200 is stiffer: Young's modulus 117 GPa against 110 GPa for Brass C260, so the same part in Copper C12200 deflects less under the same load.

Which is lighter for the same job, Brass C260 or Copper C12200?

For the same stiffness or strength: Brass C260 is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate; Copper C12200 is lighter for a stiff rod or tie (tension).

Part that must beBrass C260Copper C12200
Stiff rod or tie (tension)1% heavierlighter
Stiff beam (bending)lighter2% heavier
Stiff panel or platelighter3% heavier
Strong rod or tielighter5.24x heavier
Strong beamlighter3.07x heavier
Strong panel or platelighter2.35x 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 C260 or Copper C12200?

Copper C12200 stretches further before it breaks: 45% elongation at break against 23% for Brass C260.

Thermal

Which conducts heat better, Brass C260 or Copper C12200?

Copper C12200 conducts heat better: 339 W/m·K against 121 W/m·K for Brass C260.

Which expands less with temperature?

Copper C12200 expands less: 16.9 µm/m·K against 20 µm/m·K for Brass C260.
