Questions
Is Brass C360 stronger than Ceramic Alumina 96%?
Brass C360 is stronger: its yield strength is 310 MPa against tensile strength 221 MPa for Ceramic Alumina 96% (40%).
Which is lighter, Brass C360 or Ceramic Alumina 96%?
Ceramic Alumina 96% is lighter: 3,720 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or Ceramic Alumina 96%?
Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 96.5 GPa for Brass C360, so the same part in Ceramic Alumina 96% deflects less under the same load.
Which is lighter for the same job, Brass C360 or Ceramic Alumina 96%?
For the same stiffness or strength: Ceramic Alumina 96% 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 C360 | Ceramic Alumina 96% |
|---|---|---|
| Stiff rod or tie (tension) | 7.17x heavier | lighter |
| Stiff beam (bending) | 4.05x heavier | lighter |
| Stiff panel or plate | 3.35x heavier | lighter |
| Strong rod or tie | 1.63x heavier | lighter |
| Strong beam | 1.82x heavier | lighter |
| Strong panel or plate | 1.93x 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 C360 or Ceramic Alumina 96%?
Brass C360 conducts heat better: 116 W/m·K against 24.7 W/m·K for Ceramic Alumina 96%.
Which expands less with temperature?
Ceramic Alumina 96% expands less: 8.2 µm/m·K against 20.5 µm/m·K for Brass C360.
