Detailed Product Description


Product Overview


Our flanged perforated alumina ceramic sleeve is manufactured from high purity 99% alumina ceramic material. This precision machined ceramic bushing features evenly distributed side holes and integrated flange structure, combining outstanding high temperature resistance, electrical insulation, ultra-low wear and excellent corrosion resistance. Widely customized and applied in industrial furnaces, welding equipment, semiconductor machinery, fluid transmission and precision automation equipment as insulating sleeves, guide nozzles and flow distribution bushings.


Material Advantage
1:Extreme High Temperature Resistance
Working temperature up to 1600℃, stable performance under long-term high-temperature furnace environment, no deformation or cracking.
2:Superior Electrical Insulation
High volume resistivity, effectively isolate current, prevent electric leakage, ideal for electronic and welding insulation components.
3:Excellent Wear & Abrasion Resistance
Hardness close to sapphire, far higher than metal and plastic, long service life under continuous friction operation.
4:Strong Chemical Corrosion Resistance
Resist acid, alkali, molten metal erosion, not react with most chemical liquids and high-temperature molten materials.
5:Low Thermal Expansion & High Thermal Conductivity
Stable dimensional accuracy under temperature fluctuation, fast heat dissipation to avoid component overheating failure.
6:Smooth Dense Surface
Polished ceramic inner & outer wall, low friction coefficient, no material adhesion during working.


Product Feature
1:Integrated flange design: Easy installation, fixed positioning without extra fixtures
2:Multi-hole perforated structure: Uniform gas/liquid circulation, balanced internal pressure
3:Precision CNC machined: Strict tolerance control for inner diameter, outer diameter, hole position and flange size
4:Uniform white dense alumina body: No pores, no impurities, consistent batch quality
5:Customizable size: Support custom inner/outer diameter, height, hole quantity, hole diameter and flange thickness

Application
  • Industrial High-temperature Furnace: Heating zone insulation sleeves, gas circulation guide tubes
  • Welding & Cutting Equipment: Welding gun insulating nozzles, arc isolation ceramic bushings
  • Semiconductor & Electronic Industry: Insulating guide sleeves for precision automated machines
  • Fluid & Gas Delivery Equipment: Flow distribution ceramic sleeves, filter guide tubes
  • Textile Machinery: High-speed yarn guide ceramic bushings
  • Laboratory High-temperature Instrument: Corrosion-resistant ceramic fixture sleeves
