Questions
Is Drywall stronger than Nickel Inconel 718?
Nickel Inconel 718 is stronger: its yield strength is 1,207 MPa against tensile strength 1.5 MPa for Drywall (805x).
Which is stiffer, Drywall or Nickel Inconel 718?
Nickel Inconel 718 is stiffer: Young's modulus 200 GPa against 1.5 GPa for Drywall, so the same part in Nickel Inconel 718 deflects less under the same load.
Which expands less with temperature?
Nickel Inconel 718 expands less: 13.2 µm/m·K against 16.7 µm/m·K for Drywall.
