Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
SLS PA12 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Magnesium AZ31B-H24 stronger than SLS PA12 Nylon?
Magnesium AZ31B-H24 is stronger: its yield strength is 220 MPa against tensile strength 48 MPa for SLS PA12 Nylon (4.58x).
Which is lighter, Magnesium AZ31B-H24 or SLS PA12 Nylon?
SLS PA12 Nylon is lighter: 930 kg/m³ against 1,769 kg/m³ for Magnesium AZ31B-H24.
Which is stiffer, Magnesium AZ31B-H24 or SLS PA12 Nylon?
Magnesium AZ31B-H24 is stiffer: Young's modulus 44.8 GPa against 1.65 GPa for SLS PA12 Nylon, 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 SLS PA12 Nylon?
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, strong panel or plate.
| Part that must be | Magnesium AZ31B-H24 | SLS PA12 Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 14.3x heavier |
| Stiff beam (bending) | lighter | 2.74x heavier |
| Stiff panel or plate | lighter | 1.58x heavier |
| Strong rod or tie | lighter | 2.41x heavier |
| Strong beam | lighter | 45% heavier |
| Strong panel or plate | lighter | 13% 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).
