Questions Is Plastic PTFE stronger than Solder SAC305? Solder SAC305 is stronger: its yield strength is 22 MPa against 9 MPa for Plastic PTFE (2.44x).
Which is lighter, Plastic PTFE or Solder SAC305? Plastic PTFE is lighter: 2,160 kg/m³ against 7,350 kg/m³ for Solder SAC305.
Which is lighter for the same job, Plastic PTFE or Solder SAC305? For the same stiffness or strength: Plastic PTFE is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic PTFE Solder SAC305 Strong rod or tie lighter 39% heavier Strong beam lighter 1.88x heavier Strong panel or plate lighter 2.18x 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).
