    Benefits of our alumina ceramic tube

    1. Chemical corrosion resistance under high temperature, even if with strong acid or alkali

    2. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel

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

    4. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.

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

    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


    Description of the alumina ceramic tube

    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 made from a selection of different purity material, 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.
