5052-H32, Kaiser Aluminum tube & pipe typical datasheet (mechanical, CTE, melting); MIL-HDBK-5J (Poisson, density, specific heat)
Celanese Fortron 1140L4 (PPS, 40% glass fibre), injection moulding; FORTRON PPS Short-Term Properties Guide (PPS-012, 2016); thermal conductivity and Poisson for 40% glass-reinforced Fortron from the Fortron PPS Design Manual (PPS-050, 2013).
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions
Is Aluminum 5052-H32 stronger than Plastic PPS GF40?
Aluminum 5052-H32 is stronger: its yield strength is 195 MPa against tensile strength 195 MPa for Plastic PPS GF40 (0%).
Which is lighter, Aluminum 5052-H32 or Plastic PPS GF40?
Plastic PPS GF40 is lighter: 1,650 kg/m³ against 2,685 kg/m³ for Aluminum 5052-H32.
Which is stiffer, Aluminum 5052-H32 or Plastic PPS GF40?
Aluminum 5052-H32 is stiffer: Young's modulus 70 GPa against 14.7 GPa for Plastic PPS GF40, so the same part in Aluminum 5052-H32 deflects less under the same load.
Which is lighter for the same job, Aluminum 5052-H32 or Plastic PPS GF40?
For the same stiffness or strength: Aluminum 5052-H32 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; Plastic PPS GF40 is lighter for a strong rod or tie, strong beam, strong panel or plate.

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 5052-H32 or Plastic PPS GF40?
Aluminum 5052-H32 conducts heat better: 138 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 23.8 µm/m·K for Aluminum 5052-H32.
