High - Temperature Ceramic Insulation 95% 99% 99.5% High Alumina Ceramic Tube
Aluminum Oxide (Alumina, Al2O3) is the most extensively used advanced ceramic material due to their outstanding property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.
Alumina ceramic tubes generally used as a kind of standard protection part, so our facility has many selections of stocks. Our vast, readily-available inventory allows us to supply our customer’s ceramic tube needs immediately, even for hard-to-find or specialty products. Aluminas are used in a variety of general-purpose applications, and their grade is chosen based on the application environment. Additionally, different purity alumina can be formulated in our factory if needed for more demand applications
Specification of the 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, the inner diameter can be 0.01mm, the overall length can be 0.01mm
5. Surface treatment: External and internal surface to be polished, glazed or metallized
6. Secondary processing: CNC machining, lapping, grinding, precision cutting and so on
Main 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 us in many high voltage, high-current application
