Questions Mechanical Is Aluminum 7050-T7451 stronger than Brass C360? Aluminum 7050-T7451 is stronger: its yield strength is 469 MPa against 310 MPa for Brass C360 (1.51x).
Which is lighter, Aluminum 7050-T7451 or Brass C360? Aluminum 7050-T7451 is lighter: 2,830 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Aluminum 7050-T7451 or Brass C360? Brass C360 is stiffer: Young's modulus 96.5 GPa against 70.3 GPa for Aluminum 7050-T7451, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Aluminum 7050-T7451 or Brass C360? For the same stiffness or strength: Aluminum 7050-T7451 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 7050-T7451 Brass C360 Stiff rod or tie (tension) lighter 2.19x heavier Stiff beam (bending) lighter 2.56x heavier Stiff panel or plate lighter 2.7x heavier Strong rod or tie lighter 4.54x heavier Strong beam lighter 3.96x heavier Strong panel or plate lighter 3.69x 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, Aluminum 7050-T7451 or Brass C360? Brass C360 stretches further before it breaks: 25% elongation at break against 11% for Aluminum 7050-T7451.
Thermal Which conducts heat better, Aluminum 7050-T7451 or Brass C360? Aluminum 7050-T7451 conducts heat better: 157 W/m·K against 116 W/m·K for Brass C360.
Which expands less with temperature? Brass C360 expands less: 20.5 µm/m·K against 23.5 µm/m·K for Aluminum 7050-T7451.
