The specification of Alumina Ceramic Tube
Material options Different purity of alumina, zirconia, silicon carbide, silicon nitride and aluminum nitride Forming methods Extrusion, dry pressed, hot pressed, ceramic injection molding and ISO pressed Dimension capability Outer diameter can be 1mm, max. to be 800mm, min. thickness can be 0.3mm Tolerance OD can be 0.005mm, ID can be 0.01mm, length can be 0.001mm Secondary process CNC machining, precision grinding, lapping, drilling, threading and laser cutting Surface finish External and internal surface to be polished, lapped, glazed or metalized and so on
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
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
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.
Remark:
We are able to achieve a variety of special requirement of ceramic tubes, including different materials,
different designs, different geometries.
