Zirconia Ceramic High Temperature Nozzle ZCN Series Custom Precision Machined 1600°C Rated for Plasma Welding Spray Use

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
