Alumina Ceramic tubes have exceptional hardness and strength, resistance to chemical attack and wear, low dielectric loss and excellent electrical insulation properties. Additionally, Alumina can be metallized for brazing to other metals, highly polished, and comes in a variety of purities depending on it use. Due to these outstanding properties ceramic Alumina tubes are used in a wide range of industrial and advanced applications.
high temperature ceramic tubes or pipes is a unique advanced ceramic. Products manufactured from alumina ceramic exhibit superior mechanical properties such as high strength and flexibility. Heat insulating propertiesand oxygen-ion conductivity indicate zirconia has potential for use in a wide variety of applications - everything from telecommunications to the new energy of the future and environmentally beneficial products.
