Main characteristics of alumina ceramic tube
1.Outstanding wear resistance, over 276 times in comparison with traditional stainless steel
2.Great mechanical properties, with diamond-like hardness, excellent compressive and dense body
3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H2SO4
4. Extraordinary electrical insulation, it always used in various high voltage, high-current application
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%), makes alumina 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 structural ceramics, so these alumina ceramic tubes are with special shapes, such as flanged, stepped, slotted, multiple holes, half tube, threaded, and so on.
