Questions
Is Ceramic Alumina 96% stronger than Copper C110?
Ceramic Alumina 96% is stronger: its tensile strength is 221 MPa against yield strength 69 MPa for Copper C110 (3.2x).
Which is lighter, Ceramic Alumina 96% or Copper C110?
Ceramic Alumina 96% is lighter: 3,720 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Ceramic Alumina 96% or Copper C110?
Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 117 GPa for Copper C110, so the same part in Ceramic Alumina 96% deflects less under the same load.
Which is lighter for the same job, Ceramic Alumina 96% or Copper C110?
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 | Ceramic Alumina 96% | Copper C110 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 6.19x heavier |
| Stiff beam (bending) | lighter | 3.85x heavier |
| Stiff panel or plate | lighter | 3.29x heavier |
| Strong rod or tie | lighter | 7.67x heavier |
| Strong beam | lighter | 5.21x heavier |
| Strong panel or plate | lighter | 4.29x 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).
