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 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 standard protection part, so our facility has many stock 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 demand applications.

Products 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, silicon carbide, and so on.
