Main characteristics of alumina ceramic tubes
1. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.
2. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
3. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel
4. Extraordinary electrical insulation, it always us in many high voltage, high-current application
5. Chemical corrosion resistance under high temperature, even if with strong acid or alkali
6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
7. Low material cost in high-level applications than other technical ceramics

The Description of alumina ceramic tubes
We provide numerous different types of alumina ceramic tubes in order to meet physical special needs, typical types including shaped tubes, slotted tubes, threaded tubes, square tubes, and so on. They can be made from a selection of different purity materials, including 96%, 99%, 99.5%, and 99.8%. All these ceramic tubes can be shaped by hot pressing, dry pressing, ceramic injection mold, or extrusion.
All alumina tubes offer high-temperature resistance, strong hardness, wear resistance, electrical insulation, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. 
Additionally, ceramic alumina tubes can be metalized to bond with metal parts, also it can be polished to mirror surface comes to the specific use.
