Alumina ceramic tubes are tubular structures made from high-purity alumina through various processing procedures.Alumina tube has excellent mechanical properties such as high hardness and good wear resistance. As for heat resistance, it can withstand high temperatures of 1600°C and maintain stable performance. As a component, it can greatly extend the service life of the equipment.
Our alumina ceramic tube series include non-porous alumina ceramic tubes, single-hole alumina tubes and alumina thermocouple protection tubes. These products are the ideal choice for various industries with their excellent performance and wide range of applications.
Nonporous Alumina Ceramic Tubes：Non-porous alumina ceramic tubes have almost no pores and a density of more than 3.9g/cm³. They have very excellent mechanical strength and can maintain stable performance in the most severe high-temperature environments. Non-porous ceramic tubes are chemically resistant and suitable for extreme chemical environments, and at high temperatures, usually up to 1600°C, and have excellent electrical insulation properties. These characteristics make them ideal for industrial equipment, electronic components and other equipment.
Alumina Single Bore Tubes：Our single hole alumina tubes are simple in design. This type of ceramic tube has only one through hole inside. It has excellent properties such as high temperature resistance and corrosion resistance, and is suitable for a variety of uses, such as laboratory equipment, thermocouple protection, heating elements and mechanical parts. Ceramic tubes come in a variety of sizes, ranging from 1mm to 100mm in diameter, and can be customized in size and purity according to your needs.
Alumina Thermocouple Protection Tubes：Thermocouple protection tube is an alumina ceramic tube designed specifically for protecting thermocouples. It can operate stably for a long time in extreme high temperature environments. It also has high temperature stability, wear resistance and oxidation resistance, which can effectively protect thermocouples and increase their service life.The protective tubes we produce usually have a purity of 99.8%, and the products contain only a very small amount of flux (silica concentration is extremely low, less than 100 ppm). While protecting the precious metal platinum thermocouples from being contaminated by silica, the alumina Superior thermal conductivity also ensures accurate temperature measurement.
Ceramic tubes for furnaces: This kind of ceramic tubes are widely used in various high-temperature furnace equipment and heat treatment applications to help with sintering, synthesis and other processes. Common application equipment include heat treatment furnaces, high-temperature experimental furnaces, atmosphere furnaces, vacuum furnaces, melting furnaces, etc. This kind of Ceramic tubes need to withstand extreme high temperatures. Our ceramic tubes for furnaces can withstand temperatures of 1600-1800 degrees Celsius, which can very effectively improve the efficiency and service life of the furnace. At the same time, the price is advantageous, which can effectively help you reduce costs.
The alumina ceramic tubes produced by Gorgeous strictly follow reasonable dimensional tolerances and quality assurance, and present you with the most competitive prices. Typical alumina ceramic tube diameters are between 1mm and 100mm. In addition, you can also send us drawings to customize the alumina ceramic tubes of the size or special shape you require.
