High Insulation Custom Technical Ceramic Tubes

The prime characteristics of Alumina Ceramic Tube

1. Outstanding wear resistance, over 276 times in comparison with stainless steel
2. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4
4. Extraordinary electrical insulation, it always use in many high voltage, high-current application

The specification of the Alumina Ceramic tube

1. Material options: different purity alumina (from 95% to 99.8%), zirconia, Silicon carbide, steatite
2. Forming methods: Extrusion, Dry pressed, Hot pressed, Ceramic Injection molding, ISO pressed
3. Dimension capability: Min. the inner diameter can be 1mm, Max. the outer diameter can be 800mm
4. Tolerance: outer diameter can be 0.005mm, inner diameter can be 0.01mm, overall length can be 0.01mm
5. Surface treatment: External and internal surface to be lappend, polished, glazed or metallized
6. Secondary processing: CNC machining, lapping, grinding, drilling, threaded,precision cutting and so on

The description of alumina ceramic tube

We provide a selection of different purity material for alumina ceramic tubes, including 96%, 99%, 99.5%, and 99.8%. All these ceramic tubes can be shaped by hot pressing, dry pressing, ceramic injection mold or extrusion.
All alumina tubes offer high-temperature resistance, strong hardness, wear resistance, electrical insulation, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Our alumina furnace tubes, alumina thermocouple protection tubes, and insulators are available in a variety of diameters and lengths with sufficient stock.
The various complex configuration of ceramic tube, like round, square, rectangular, hex, flanged, double-bores, tri-bores,muti-bores, one end open, etc are available to us.
Additionally, ceramic alumina tubes can be metalized to bond with metal parts, also it can be polished to mirror surface comes to the specific use.
