Questions Mechanical Is Brass C260 stronger than Stainless Steel 303? Brass C260 is stronger: its yield strength is 345 MPa against 275 MPa for Stainless Steel 303 (25%).
Which is lighter, Brass C260 or Stainless Steel 303? Stainless Steel 303 is lighter: 7,900 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Stainless Steel 303? Stainless Steel 303 is stiffer: Young's modulus 200 GPa against 110 GPa for Brass C260, so the same part in Stainless Steel 303 deflects less under the same load.
Which is lighter for the same job, Brass C260 or Stainless Steel 303? For the same stiffness or strength: Brass C260 is lighter for a strong rod or tie, strong beam, strong panel or plate; Stainless Steel 303 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate.
Part that must be Brass C260 Stainless Steel 303 Stiff rod or tie (tension) 1.96x heavier lighter Stiff beam (bending) 45% heavier lighter Stiff panel or plate 32% heavier lighter Strong rod or tie lighter 16% heavier Strong beam lighter 8% heavier Strong panel or plate lighter 4% 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 Stainless Steel 303? Stainless Steel 303 stretches further before it breaks: 35% elongation at break against 23% for Brass C260.
Thermal Which conducts heat better, Brass C260 or Stainless Steel 303? Brass C260 conducts heat better: 121 W/m·K against 15 W/m·K for Stainless Steel 303.
Which expands less with temperature? Stainless Steel 303 expands less: 16 µm/m·K against 20 µm/m·K for Brass C260.
