Questions Is Brass C260 stronger than Plastic UHMWPE? Brass C260 is stronger: its yield strength is 345 MPa against 20 MPa for Plastic UHMWPE (17.3x).
Which is lighter, Brass C260 or Plastic UHMWPE? Plastic UHMWPE is lighter: 930 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or Plastic UHMWPE? Brass C260 is stiffer: Young's modulus 110 GPa against 0.66 GPa for Plastic UHMWPE, so the same part in Brass C260 deflects less under the same load.
Which is lighter for the same job, Brass C260 or Plastic UHMWPE? For the same stiffness or strength: Brass C260 is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie; Plastic UHMWPE is lighter for a stiff panel or plate, strong beam, strong panel or plate.
Part that must be Brass C260 Plastic UHMWPE Stiff rod or tie (tension) lighter 18.2x heavier Stiff beam (bending) lighter 41% heavier Stiff panel or plate 1.66x heavier lighter Strong rod or tie lighter 1.88x heavier Strong beam 37% heavier lighter Strong panel or plate 2.21x heavier lighter
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, Brass C260 or Plastic UHMWPE? Brass C260 conducts heat better: 121 W/m·K against 0.4 W/m·K for Plastic UHMWPE.
Which expands less with temperature? Brass C260 expands less: 20 µm/m·K against 200 µm/m·K for Plastic UHMWPE.
