Main characteristics of alumina ceramic tube

1. Extraordinary electrical insulation, it always us in many high voltage, high-current application

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

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

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

 

The description of the micro-ceramic tube

 

We supply a board range of alumina ceramic tubes, including small-sized part to large-sized part,  different levels of purity from 40% to 99.9%, also a selection of color, customized geometries are available.

Alumina ceramic tubes generally used as a kind of standard protection part, Micro-ceramic tubes are regularly shaped or formed by extrusion or ceramic injection molding, then with necessary precise grinding to achieve the tighten dimensional size.

Our facility has many selections of stocks with standard sizes for alumina ceramic tubes. Our vast, readily-available inventory allows us to supply our customer’s ceramic tube needs immediately, even for hard-to-find or specialty products.
