Questions
Is Brick stronger than DMLS AlSi10Mg Aluminum?
DMLS AlSi10Mg Aluminum is stronger: its yield strength is 270 MPa against tensile strength 5.1 MPa for Brick (52.9x).
Which is lighter, Brick or DMLS AlSi10Mg Aluminum?
Brick is lighter: 2,082 kg/m³ against 2,670 kg/m³ for DMLS AlSi10Mg Aluminum.
Which is lighter for the same job, Brick or DMLS AlSi10Mg Aluminum?
For the same stiffness or strength: DMLS AlSi10Mg Aluminum is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brick | DMLS AlSi10Mg Aluminum |
|---|---|---|
| Strong rod or tie | 41.3x heavier | lighter |
| Strong beam | 11x heavier | lighter |
| Strong panel or plate | 5.67x heavier | lighter |
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).
