Questions
Is Aluminum 2024-T351 stronger than Brick?
Aluminum 2024-T351 is stronger: its yield strength is 324 MPa against tensile strength 5.1 MPa for Brick (63.5x).
Which is lighter, Aluminum 2024-T351 or Brick?
Brick is lighter: 2,082 kg/m³ against 2,770 kg/m³ for Aluminum 2024-T351.
Which is lighter for the same job, Aluminum 2024-T351 or Brick?
For the same stiffness or strength: Aluminum 2024-T351 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Aluminum 2024-T351 | Brick |
|---|---|---|
| Strong rod or tie | lighter | 47.8x heavier |
| Strong beam | lighter | 12x heavier |
| Strong panel or plate | lighter | 5.99x 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).
