Main characteristics of alumina ceramic tubes1. High-temperature resistance, up to 2000ºC in the vacuum atmosphere2. Outstanding wear resistance, over 276 times in comparison with traditional stainless steel3. Great mechanical properties, offers diamond-like hardness to be HRA85 4. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HCL, H2SO45. Extraordinary electrical insulation, it always used in various high voltage, high-current application6. High-precision dimensions with ideal fitting relationship
The Description of alumina ceramic tubes
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its 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 are 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 applicationsProducts category

Remark:

We are dealing with a variety of advanced ceramic tubes in a selection of raw materials, mainly including alumina, zirconia, silicon nitride, aluminum nitride, and silicon carbide, and so on.
