Product Description

Product Description

     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 increase, so alumina is grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, and 99.9% alumina.

    Alumina ceramic tubes are generally used as a kind of standard protection part, so our facility has many selections. Our vast, readily available inventory allows us to supply our customers' 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 demanding applications.
