Alumina ceramic tube is formed by isostatic pressing process, with regular size and complete specifications, and has the characteristics of high purity, good compactness, good wear resistance, corrosion resistance, high temperature resistance, low wear, and no contamination by abrasives. The content of alumina can be 99%, 95%, 92%. 
Alumina ceramic long tube combines the advantages of high alumina hardness, good chemical inertness and steel, with excellent wear resistance, corrosion resistance, heat resistance, thermal shock resistance and mechanical shock resistance, and its service life is 15 times longer than that of ordinary steel pipes above. Alumina ceramic pipes are generally white. Because the material has the characteristics of low thermal expansion, corrosion resistance, high thermal conductivity, good insulation, high mechanical strength and good wear resistance. In addition, in the field of electronic ceramics, many alumina ceramics are also used as insulators. In addition, many of the faucet valves, ceramic tubes, ceramic screws, etc. can be made of alumina. Generally speaking, as people's understanding of this material continues to deepen, its application becomes wider and wider, and its price naturally becomes lower and lower. Due to its excellent electrical performance at high frequencies, it has low dielectric loss, high volume resistivity, high strength, high hardness, small linear expansion coefficient, and good wear resistance and heat resistance. It is more economical and practical to use 95% alumina ceramics in general occasions. 99% to 99.9% alumina porcelain is only used for occasions with particularly high performance requirements. 
Alumina ceramics have the advantages of low thermal expansion, high thermal conductivity, high mechanical strength and good wear resistance. The use of alumina ceramics is to resist the erosion of gold and slag, and can also be used as special refractory materials, wear-resistant parts and tool materials in the machinery industry, and insulators in the electronics industry and other industries.
