Questions
Is Brass C260 stronger than DMLS 316L Stainless Steel?
DMLS 316L Stainless Steel is stronger: its yield strength is 530 MPa against 345 MPa for Brass C260 (1.54x).
Which is lighter, Brass C260 or DMLS 316L Stainless Steel?
DMLS 316L Stainless Steel is lighter: 7,900 kg/m³ against 8,525 kg/m³ for Brass C260.
Which is stiffer, Brass C260 or DMLS 316L Stainless Steel?
DMLS 316L Stainless Steel is stiffer: Young's modulus 185 GPa against 110 GPa for Brass C260, so the same part in DMLS 316L Stainless Steel deflects less under the same load.
Which is lighter for the same job, Brass C260 or DMLS 316L Stainless Steel?
For the same stiffness or strength: DMLS 316L Stainless Steel 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 | Brass C260 | DMLS 316L Stainless Steel |
|---|---|---|
| Stiff rod or tie (tension) | 1.81x heavier | lighter |
| Stiff beam (bending) | 40% heavier | lighter |
| Stiff panel or plate | 28% heavier | lighter |
| Strong rod or tie | 1.66x heavier | lighter |
| Strong beam | 44% heavier | lighter |
| Strong panel or plate | 34% 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).
Which conducts heat better, Brass C260 or DMLS 316L Stainless Steel?
Brass C260 conducts heat better: 121 W/m·K against 16.2 W/m·K for DMLS 316L Stainless Steel.
Which expands less with temperature?
DMLS 316L Stainless Steel expands less: 15.7 µm/m·K against 20 µm/m·K for Brass C260.
