Threaded Alumina Ceramic Tube
The description of the threaded ceramic tube
The alumina threaded ceramic tube not only offers high mechanical strength, great toughness, exceptional wear resistance, impact resistance, but also high-temperature resistance, excellent electrical insulation and chemical stability. The threaded ceramic tube are usually machined to get high precision dimensions.
High alumina ceramic tube is made of high purity aluminum oxide range from 95% to 99.5%, all of them have a dense body through dry pressed, hot pressed, and so on.
Our facility has many selections of stocks with standard sizes for alumina ceramic tubes. Our vast, readily-available inventory allows us to supply our customer’s ceramic tube needs immediately, even for hard-to-find or specialty products.
Specification of the ceramic tube
1. Forming methods: Extrusion, Dry pressed, Hot pressed, Ceramic Injection molding, ISO pressed
2. Material options: different purity alumina (from 95% to 99.8%), zirconia, Silicon carbide, steatite
3. Dimension capability: Min. the inner diameter can be 1mm, Max. the outer diameter can be 800mm
4. Secondary processing: CNC machining, lapping, grinding, precision cutting and so on
5. Tolerance: outer diameter can be 0.005mm, the inner diameter can be 0.01mm, the overall length can be 0.01mm
6. Surface treatment: External and internal surface to be polished, glazed or metalized
Main characteristics of the threaded ceramic tube
1. Extraordinary electrical insulation, it always us in many high voltage, high-current application
2. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4
3. Outstanding wear resistance, over 276 times in comparison with stainless steel
4. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
