Questions Is Aluminum ADC12 stronger than Brass C260? Brass C260 is stronger: its yield strength is 345 MPa against 149 MPa for Aluminum ADC12 (2.32x).
Which is lighter, Aluminum ADC12 or Brass C260? Aluminum ADC12 is lighter: 2,680 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Aluminum ADC12 or Brass C260? Brass C260 is stiffer: Young's modulus 110 GPa against 79.8 GPa for Aluminum ADC12, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Aluminum ADC12 or Brass C260? For the same stiffness or strength: Aluminum ADC12 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 Aluminum ADC12 Brass C260 Stiff rod or tie (tension) lighter 2.3x heavier Stiff beam (bending) lighter 2.71x heavier Stiff panel or plate lighter 2.86x heavier Strong rod or tie lighter 37% heavier Strong beam lighter 1.82x heavier Strong panel or plate lighter 2.09x 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, Aluminum ADC12 or Brass C260? Aluminum ADC12 conducts heat better: 125 W/m·K against 121 W/m·K for Brass C260.
Which expands less with temperature? Brass C260 expands less: 20 µm/m·K against 21 µm/m·K for Aluminum ADC12.
