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.
