Alumina Tube
Alumina Tube
Alumina (Al2O3) is a ceramic material commonly used in high temperature and high-wear applications. Alumina tubes are used in a variety of industrial applications, including as a lining for furnace walls, as a protective covering for thermocouples, and as a support structure for catalysts. They have excellent thermal stability and corrosion resistance, and can withstand temperatures up to 1700°C. Alumina tubes are also used in laboratory equipment, such as in high-temperature tube furnaces.

At CG Material, we offer high quality Alumina Tubes with exceptional purity and precision in terms of size. Our products range in size from 1mm to 100mm and have a purity level of up to 99.8%. We also provide custom manufacturing options for special shapes to meet specific needs.
Description of Alumina Tube
Alumina is a fine ceramic material that is widely used in a lot of industries. Alumina tubes have superb performances in electrical insulation, high chemical resistance, and low thermal expansion, and these ceramic tubes are widely used in industrial ovens and machines. High purity alumina materials are excellent for making alumina components for CVD, ion implants, photolithography, and semiconductor manufacturing. In traditional industries, alumina tubes are ideal for products such as injector tubes and insulators. Alumina tubes are also widely used as protectors for high-temperature thermal couples.
