Questions Is Aluminum A380 stronger than Plastic PTFE? Aluminum A380 is stronger: its yield strength is 160 MPa against 9 MPa for Plastic PTFE (17.8x).
Which is lighter, Aluminum A380 or Plastic PTFE? Plastic PTFE is lighter: 2,160 kg/m³ against 2,713 kg/m³ for Aluminum A380.
Which is lighter for the same job, Aluminum A380 or Plastic PTFE? For the same stiffness or strength: Aluminum A380 is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Aluminum A380 Plastic PTFE Strong rod or tie lighter 14.2x heavier Strong beam lighter 5.42x heavier Strong panel or plate lighter 3.36x 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 conducts heat better, Aluminum A380 or Plastic PTFE? Aluminum A380 conducts heat better: 96.2 W/m·K against 0.25 W/m·K for Plastic PTFE.
Which expands less with temperature? Aluminum A380 expands less: 21.8 µm/m·K against 100 µm/m·K for Plastic PTFE.
