Questions
Is Aluminum 7075-T6 stronger than Brick?
Aluminum 7075-T6 is stronger: its yield strength is 503 MPa against tensile strength 5.1 MPa for Brick (98.6x).
Which is lighter, Aluminum 7075-T6 or Brick?
Brick is lighter: 2,082 kg/m³ against 2,800 kg/m³ for Aluminum 7075-T6.
Which is lighter for the same job, Aluminum 7075-T6 or Brick?
For the same stiffness or strength: Aluminum 7075-T6 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Aluminum 7075-T6 | Brick |
|---|---|---|
| Strong rod or tie | lighter | 73.3x heavier |
| Strong beam | lighter | 15.9x heavier |
| Strong panel or plate | lighter | 7.38x 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).
