The description of alumina ceramic tube
Alumina (Al2O3) is the most commonly used industrial ceramic material due to its high mechanical strength, this high-performance. It results in suitable for use in many future-oriented processes. Additionally, the outstanding chemical resistance, great thermal properties and favorable cost of aluminum oxide (Al2O3 content > 90%), it makes alumina as a perfect material for many industries, from electrical applications and high-temperature applications.
Ceramic alumina tubes are found in a variety of electrical/electronic devices, engineering equipment that works as a Structural Ceramics, so these alumina ceramic tubes are with special shapes, such as flanged, stepped, slotted, multiple holes, half tube, threaded and so on.
Remark:
We are able to achieve a variety of special requirement of ceramic tubes, including different materials,
different designs, different geometries.
