Product Description

Customized Large Size Al2O3 Ceramic Hollow Tube

The description of alumina al2o3 ceramic hollow tube

Alumina (Al2O3) is a superb hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments. Our facility offers alumina with various purity levels which ranges from 75% to 99.8%. The level of purity, grain size, and density required is dependent on the rigors of the application and the component configuration.

Currently, we have been supplying a broad range of ceramic tube, inclding different design, different specification, different surface treatment and so on. All these ceramic tube can be machined at our own factory to cater to customers' specific needs.

The specification of the al2o3 ceramic hollow tube

1. Forming methods: dry pressed, hot pressed, extrusion, ceramic Injection molding, Isostatic pressed

2. Material options: alumina ( purity range from 95% to 99.8%), zirconia,silicon nitride, boron nitride

3. Dimension capability: the min. inner diameter can be 1mm, the max. outer diameter up to be 800mm

4. Available design: both ends open, one end closed, multiply holes, side-slot, steps, threaded, half tubes.

5. Secondary processing: CNC machining, lapping, grinding, drilling, threaded,precision cutting and so on

6. Tolerance: outer diameter can be 0.005mm, inner diameter can be 0.01mm, overall length can be 0.01mm

7. Surface treatment: external and internal surface to be lappend, polished, glazed or metallized

The prime characteristics of Alumina Ceramic tube

1. High temperature resistance, it can withstand up to 1750℃ in the air condition, but up to 2200℃ in vacuum atmosphere

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

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