Questions

Is Copper C110 stronger than Plastic PPS GF40?

Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against yield strength 69 MPa for Copper C110 (2.83x).

Which is lighter, Copper C110 or Plastic PPS GF40?

Plastic PPS GF40 is lighter: 1,650 kg/m³ against 8,913 kg/m³ for Copper C110.

Which is stiffer, Copper C110 or Plastic PPS GF40?

Copper C110 is stiffer: Young's modulus 117 GPa against 14.7 GPa for Plastic PPS GF40, so the same part in Copper C110 deflects less under the same load.

Which is lighter for the same job, Copper C110 or Plastic PPS GF40?

For the same stiffness or strength: Copper C110 is lighter for a stiff rod or tie (tension); Plastic PPS GF40 is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must be	Copper C110	Plastic PPS GF40
Stiff rod or tie (tension)	lighter	48% heavier
Stiff beam (bending)	1.91x heavier	lighter
Stiff panel or plate	2.7x heavier	lighter
Strong rod or tie	15.3x heavier	lighter
Strong beam	10.8x heavier	lighter
Strong panel or plate	9.08x 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, Copper C110 or Plastic PPS GF40?

Copper C110 conducts heat better: 391 W/m·K against 0.2 W/m·K for Plastic PPS GF40.

Which expands less with temperature?

Plastic PPS GF40 expands less: 12 µm/m·K against 16.9 µm/m·K for Copper C110.
