Questions
Is Magnesium AZ31B-H24 stronger than Plastic Nylon PA6?
Magnesium AZ31B-H24 is stronger: its yield strength is 220 MPa against 90 MPa for Plastic Nylon PA6 (2.44x).
Which is lighter, Magnesium AZ31B-H24 or Plastic Nylon PA6?
Plastic Nylon PA6 is lighter: 1,130 kg/m³ against 1,769 kg/m³ for Magnesium AZ31B-H24.
Which is stiffer, Magnesium AZ31B-H24 or Plastic Nylon PA6?
Magnesium AZ31B-H24 is stiffer: Young's modulus 44.8 GPa against 3.5 GPa for Plastic Nylon PA6, so the same part in Magnesium AZ31B-H24 deflects less under the same load.
Which is lighter for the same job, Magnesium AZ31B-H24 or Plastic Nylon PA6?
For the same stiffness or strength: Magnesium AZ31B-H24 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam.
| Part that must be | Magnesium AZ31B-H24 | Plastic Nylon PA6 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 8.18x heavier |
| Stiff beam (bending) | lighter | 2.29x heavier |
| Stiff panel or plate | lighter | 49% heavier |
| Strong rod or tie | lighter | 1.56x heavier |
| Strong beam | lighter | 16% heavier |
| Strong panel or plate | about equal | about equal |
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, Magnesium AZ31B-H24 or Plastic Nylon PA6?
Magnesium AZ31B-H24 conducts heat better: 76.9 W/m·K against 0.33 W/m·K for Plastic Nylon PA6.
Which expands less with temperature?
Magnesium AZ31B-H24 expands less: 26.8 µm/m·K against 102 µm/m·K for Plastic Nylon PA6.
