The prime characteristics of alumina ceramic tube

1. Outstanding wear resistance, over 276 times in comparison with stainless steel

2. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4

4. Extraordinary electrical insulation, it always use in many high voltage, high-current application

The description of alumina ceramic tube

Alumina or aluminum oxide (al2o3) in its various of different grade has most extensively application than other technical ceramic materials. Alumina possesses higher hardness, super wear resistance, high compressive strength, high temerpatrue resistance, chemical stability and high electrical insulation,as well as the cost performance 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. Except for standard design both ends open ceramic tube, we also produce one end closed ceramic tube, square, rectangular, hex, double-bores, tri-bores tube.
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
