Product Description

Both Ends Open High Purity Al2O3 Tubing Alumina Ceramic Tube

Products category

We are dealing with a variety of advanced ceramic tubes in a selection of raw materials, mainly including alumina, zirconia, silicon nitride, aluminum nitride, and silicon carbide.

 

Product Introduction

Alumina (Aluminum Oxide, or Al2O3) is the most extensively used advanced ceramic material due to its outstanding properties and cost-effective advantages. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels. Common ones include 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina and 99.9% alumina.

Alumina ceramic tubes are 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

The specification of our alumina ceramic tubes

1. Material: 75% / 95% / 99% / 99.5% / 99.8% Alumina

2. Forming method: Extrusion, Dry pressed, CIM, or ISO pressed

3. Dimensional capability: ID with min.1mm,  OD with max .800mm

4. Dimensional tolerance: OD with 0.005mm, ID with 0.01mm

5. Surface treatment: polished, glazed, or metallized

6. Secondary processing: CNC machining, lapping, threaded, drilling, grinding, precision laser cutting (depending on accuracy required)

7. Shape: slotted, threaded, square, rectangular, hexagonal, flanged, with single / multiple holes, one-end closed, half-tube / half-pipe

Main characteristics of alumina ceramic tubes

1. High-temperature resistance, up to 2000ºC in the vacuum atmosphere.

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

3. Great mechanical properties, offers diamond-like hardness (Rockwell hardness to be HRA 85). 

4. Exceptional corrosion resistance, which can withstand various strong acid and alkali, like HCL and H2SO4.

5. Excellent electrical insulation, often used in various high voltage and high current situations.

6. High-precision dimensions and ideal fit.
