SC9885 Silicon Nitride Bonded Silicon Carbide Beam SNBC Beam 40 x 50 mm

Silicon Nitride Bonded Silicon Carbide Beam SNBC Beam 40 x 50 mm Description

The beam is manufactured from a composite of sintered silicon nitride and silicon carbide to combine the attributes of both ceramics. Its standard dimensions of 40 x 50 mm facilitate integration into assemblies requiring precise component fit. The thermal conductivity of 15 W/(m·k) ensures efficient heat transfer, while an operating limit of ≤1450 ℃ supports usage in high-temperature environments. A density maintained at ≥2.7 g/cm³ contributes to its mechanical integrity during thermal cycling.
