Low REsistivity Silicon Carbide
EDM Material Silicon Carbide Machining
Calix Ceramic Solutions offers a low resistivity sintered silicon carbide (SiC) that is an Electrical Discharge Machineable (EDM) material. The material’s high density and uniform low electrical resistivity allow it to be a successful EDM material.
Low Resistivity Silicon Carbide Properties
All properties are at room temperature (20°C) unless otherwise stated.
| Composition | Grain Size (μm) | Density (g/cc) | Hardness (Vickers) (GPa) | Young's Modulus | Coefficient of Thermal Expansion - 20-700°C (ppm/K) | Thermal Conductivity (W/mK) | Electrical Resitivity - Four Terminal (Ω-cm) |
|---|---|---|---|---|---|---|---|
| SiC | 4-10 | 2.90-2.96 | 15 | 256-296 | 4.1 | 140 | 10^-2 |
