Product Description
High Precision Alumina Ceramic Nozzle Wear Resistant Al2O3 Nozzle for Welding Sandblasting Fluid Control
Alumina ceramic part is produced by firing a tightly packed powder form of Al2O3 which includes some binder material. Commercially available grades range from 90% up to 99.95% with the higher purity generating somewhat higher hardness. It is possible to machine alumina using diamond grinding techniques. Polishing is also possible, with the degree attainable affected by alumina grain size and production technique, like pressed or extruded.
Our alumina ceramic nozzles are manufactured from high-purity 95%–99.7% Al₂O₃ ceramic through high-temperature sintering and precision CNC machining. Featuring ultra-high hardness, exceptional abrasion resistance and excellent chemical inertness, these nozzles outperform traditional metal nozzles in harsh working conditions, effectively resisting erosion from abrasive media, strong acids, alkalis and high-temperature fluids.
With precise inner hole tolerance and smooth polished inner walls, the alumina nozzles ensure stable and uniform flow rate, accurate spray shaping and consistent atomization effect without clogging. Boasting outstanding high-temperature resistance up to 1800°C and superior electrical insulation, they maintain stable structural and performance integrity under long-term high-temperature, high-pressure and continuous flushing scenarios.
Alumina Oxide (Al2O3) Properties:
◆ High Hardness
Strong wear resistance, durable and not easy to wear.
◆ Excellent Thermal Conductivity
The thermal conductivity at room temperature is 30~40W/(m·K), which is higher than that of steel, copper and aluminum.
◆ Good Chemical Stability
Resistant to acid, alkali and salt corrosion.
◆ High Temperature Stability
Withstands 1600℃ high temperature and has high temperature stability.
