Zirconia Ceramic High Temperature Nozzle ZCN Series Custom Precision Machined 1600°C Rated for Plasma Welding Spray Use
Zirconia ceramic high temperature nozzle
,Custom precision machined zirconia nozzle
,Plasma welding spray zirconia nozzle
The ZCN Series Zirconia Ceramic High Temperature Nozzle is purpose-built for thermal spray, plasma welding, and high-temperature industrial processes. Fabricated from high-purity magnesia-stabilized zirconia (MSZ) or yttria-stabilized zirconia (YSZ), these nozzles withstand continuous operating temperatures up to 1600°C while maintaining excellent dimensional stability and thermal shock resistance.
Key Features
- Ultra-High Temperature Rating: Continuous service up to 1600°C with exceptional thermal shock resistance, surviving rapid ΔT >800°C without cracking
- Precision CNC Machined: Custom-fabricated to tight tolerances with consistent bore geometry for stable plasma arc and spray pattern control
- Low Thermal Conductivity: Zirconia ceramic thermal conductivity of 2.0-2.5 W/m·K minimizes heat loss and improves process energy efficiency
- Excellent Erosion Resistance: Dense sintered microstructure resists particle erosion in plasma spray and powder injection applications
- Chemical Inertness: Non-reactive with molten metals, slags, and reactive gases; ideal for metallurgical and chemical process nozzles
- Custom Configurations: Available in various bore sizes, lengths, and mounting geometries to fit major OEM plasma equipment
