Main characteristics of alumina ceramic tubes
1.Outstanding wear resistance, over 276 times in comparison with traditional stainless steel
2.Great mechanical properties, with diamond-like hardness, excellent compressive and dense body
3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4
4. Extraordinary electrical insulation, it always used in various high voltage, high-current application

The Description of alumina ceramic tubes
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to their 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 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

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.
