Questions
Is Brick stronger than Nickel Inconel 718?
Nickel Inconel 718 is stronger: its yield strength is 1,207 MPa against tensile strength 5.1 MPa for Brick (237x).
Which is lighter, Brick or Nickel Inconel 718?
Brick is lighter: 2,082 kg/m³ against 8,221 kg/m³ for Nickel Inconel 718.
Which is lighter for the same job, Brick or Nickel Inconel 718?
For the same stiffness or strength: Nickel Inconel 718 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brick | Nickel Inconel 718 |
|---|---|---|
| Strong rod or tie | 59.9x heavier | lighter |
| Strong beam | 9.69x heavier | lighter |
| Strong panel or plate | 3.9x 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).
