Industrial Technical High Purity Alumina Ceramic Half Tube

The description of the ceramic tube

In order to meet some special application, we are capabile of dealing with a variety of different geometries of ceramic tube, including half tube, ceramic tube with slot, ceramic tube with step, ceramic tube with multiple holes.

With our own the state of art manufacturing process, like the selection of forming methods, sintering, high precision machinining, metalizing and electroplating and surface treatment, it greatly helps to achieve customers' toughnest requirement. You are welcome to reach us anytime if you are in need of some special shape Ceramic Tubes.

The specification of the ceramic tube

1. Material options: different purity alumina (from 95% to 99.8%), zirconia, Silicon carbide, mullite
2. Forming methods: Extrusion, Dry pressed, Hot pressed, Ceramic Injection molding, ISO pressed
3. Size capability: Min. the inner diameter can be 1mm, Max. the outer diameter can be 800mm
4. Tolerance: outer diameter can be 0.005mm, the inner diameter can be 0.01mm, the overall length can be 0.01mm
5. Surface treatment: External and internal surface to be polished, glazed or metallized
6. Secondary processing: CNC machining, lapping, grinding, precision cutting and so on

The prime features of the 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. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
4. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4
