Questions
Is Ceramic Alumina 96% stronger than Plastic Nylon PA66?
Ceramic Alumina 96% is stronger: its tensile strength is 221 MPa against yield strength 85 MPa for Plastic Nylon PA66 (2.6x).
Which is lighter, Ceramic Alumina 96% or Plastic Nylon PA66?
Plastic Nylon PA66 is lighter: 1,130 kg/m³ against 3,720 kg/m³ for Ceramic Alumina 96%.
Which is stiffer, Ceramic Alumina 96% or Plastic Nylon PA66?
Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 3 GPa for Plastic Nylon PA66, 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 Plastic Nylon PA66?
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; Plastic Nylon PA66 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Ceramic Alumina 96% | Plastic Nylon PA66 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 30.7x heavier |
| Stiff beam (bending) | lighter | 3.05x heavier |
| Stiff panel or plate | lighter | 41% heavier |
| Strong rod or tie | 27% heavier | lighter |
| Strong beam | 1.74x heavier | lighter |
| Strong panel or plate | 2.04x 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, Ceramic Alumina 96% or Plastic Nylon PA66?
Ceramic Alumina 96% conducts heat better: 24.7 W/m·K against 0.33 W/m·K for Plastic Nylon PA66.
Which expands less with temperature?
Ceramic Alumina 96% expands less: 8.2 µm/m·K against 98 µm/m·K for Plastic Nylon PA66.
