Product Description Product Description Alumina ceramic tubes are generally used as a kind of standard protection part, so our facility has many selections of stocks. Our vast, readily available inventory allows us to supply our customer's ceramic tube needs immediately, even for hard-to-find or specialty products. Aluminas are used in a variety of general-purpose applications, and their grade is chosen based on the application environment. Additionally, different purity alumina can be formulated in our factory if needed for more demand applications Alumina Ceramic is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics, pump components and automotive sensors. UNIPRETEC offers a variety of alumina compositions, including 92% , 95% , 96%, 99% , 99.5% and 99.8% Alumina, Alumina components can be formed by a variety of manufacturing techniques such as uniaxial pressing,isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining and a variety of other processes. Alumina ceramic furnace tubes are widely used in high temperature tube furnaces, the operating temperature can reach 1600 oC, and the conventional diameter is 60mm-120mm. The corundum furnace tube is an important ceramic part of the tube furnace. It is installed in the middle of the furnace. Both ends are covered with metal flanges for sealing. The material is put into the crucible and placed in the furnace tube.
