Product Description

The Description of alumina ceramic rectangular tube

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 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 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 demanding applications

Other types of alumina ceramic tubes




Remark:
We are dealing with a variety of alumina ceramic tubes in different purities, different geometries, different colors, different precision levels.
