High-Precision Silicon Nitride Ceramic Component with Compressive Strength ≥2200MPa Flexural Strength ≥750MPa and Thermal Conductivity 30-35W/(m*K)

This precision structural component is manufactured using gas-phase sintered silicon nitride ceramic, featuring a dark gray metallic luster surface. The innovative irregular trapezoidal design incorporates a positioning boss with precision circular holes at the top and four symmetrically distributed mounting holes on both sides of the bottom. The structure has been optimized through finite element analysis for lightweight performance without compromising strength. All hole positions maintain high precision with positional tolerances controlled within ±0.01mm.
