Hot Zone Thermal Shields

Tungsten-Molybdenum (W-Mo) Thermal Shields for High Temperature Furance:

Tungsten-molybdenum hot zone shielding are high-performance components designed for extreme-temperature industrial applications, such as vacuum furnaces, sintering systems, and aerospace thermal processing equipment. Combining the exceptional properties of tungsten and molybdenum, these screens deliver unparalleled thermal management, durability, and efficiency in high-heat environments.

Key Advantages of W-Mo Hot Zone Shielding

1. Ultra-High Temperature Resistance
   • Withstand continuous operation up to 2200°C (tungsten) and 1800°C (molybdenum), ideal for processes like ceramic sintering, nuclear material annealing, and advanced alloy treatment.
2. Superior Thermal Insulation
   • Multi-layer reflective design minimizes radiant heat loss, improving furnace energy efficiency by 30–40% compared to traditional graphite screens.
3. Low Thermal Expansion
   • Coefficient of thermal expansion (CTE): 4.5×10⁻⁶/°C (W) and 5.3×10⁻⁶/°C (Mo) , reducing structural stress and deformation during rapid temperature cycling.
4. High Purity & Vacuum Compatibility
   • Ultra-low outgassing rate (<1×10⁻⁶ Pa·m³/s) ensures stable vacuum environments (up to 10⁻⁵ Pa), critical for semiconductor and aerospace applications.
5. Long Service Life
   • Resistant to oxidation, creep, and thermal fatigue, offering 2–3x longer lifespan than conventional nickel-based alloys.
