High Temperature Alumina Ceramic Tube
Alumina (Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its outstanding property characteristics and cost-effective advantage. As the purity increases, both wear resistance and corrosion resistance also increase. Alumina ceramic tubes are standard protection parts used in a variety of general-purpose and specialty applications.
The Specification
- Grades: 96%, 99%, 99.5% and 99.8% alumina availability.
- Forming: Extrusion, Dry pressed, CIM, ISO pressed.
- Capability: ID min. 1mm, OD max. 800mm.
- Tolerance: OD up to 0.005mm, ID up to 0.01mm.
- Processing: CNC machining, lapping, threaded, drilling, grinding, laser cutting.
Main Characteristics
- High-temperature resistance up to 2000ºC in vacuum.
- Outstanding wear resistance (276 times better than stainless steel).
- Diamond-like hardness (HRA85).
- Exceptional corrosion resistance against strong acids (HCL, H2SO4).
- Extraordinary electrical insulation for high voltage applications.
