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 the purity increases, both wear resistance and corrosion resistance also increase, so alumina is grouped 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 applications
