Questions
Is Plastic ABS (bulk/injection) stronger than Brick?
Plastic ABS (bulk/injection) is stronger: its yield strength is 45 MPa against tensile strength 5.1 MPa for Brick (8.82x).
Which is lighter, Plastic ABS (bulk/injection) or Brick?
Plastic ABS (bulk/injection) is lighter: 1,040 kg/m³ against 2,082 kg/m³ for Brick.
Which is lighter for the same job, Plastic ABS (bulk/injection) or Brick?
For the same stiffness or strength: Plastic ABS (bulk/injection) is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Plastic ABS (bulk/injection) | Brick |
|---|---|---|
| Strong rod or tie | lighter | 17.7x heavier |
| Strong beam | lighter | 8.55x heavier |
| Strong panel or plate | lighter | 5.95x 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).
Which conducts heat better, Plastic ABS (bulk/injection) or Brick?
Brick conducts heat better: 1.02 W/m·K against 0.17 W/m·K for Plastic ABS (bulk/injection).
Which expands less with temperature?
Brick expands less: 7.2 µm/m·K against 95 µm/m·K for Plastic ABS (bulk/injection).
