High Temperature Alumina Ceramic Insulating Tube Rod

We are involved in manufacturing, exporting and supplying of High Temperature Alumina Ceramic Insulating Tube Rod in Xiamen, Fujian, China.
Our provided High Temperature Alumina Insulating Tubes are mainly used for the conditions that high temperature resistance is required.They are always used as protective tubes. Their operating temperature can be up to 1700A C.
Alumina thermocouple protection tubes also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts.
Additionally,ceramic thermocouple protection tubes have high hardness, wear resistance, insulation property,can be used as fuse insulating tube on the electric and electronic appliances.

Properties of Alumina Ceramics
Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000A C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.

Application:
Mainly used for the protection of the temperature sensor, make the temperature sensor and outside isolation, decrease or prevent components in use process by foreign materials, eroded oxidation and touch the worse.
