My factory looking for distributors.
Alumina industrial tube is a ceramic material mainly composed of alumina (Al2O3), which is used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Its Rockwell hardness is HRA80-90, second only to diamond, and far exceeds the wear resistance of wear-resistant steel and stainless steel.
Alumina ceramic materials are used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve discs;

Insulation:
Alumina insulation tube is made of a material with good insulation, which mainly separates the different pole items of the temperature measuring element to avoid interference or contact short circuit between the two poles so as to ensure accurate temperature measurement.
The conventional size of the insulating tube is 0.8mm to 10mm in outer diameter, and the holes are divided into single hole, double hole, four hole and multi-hole, with the minimum diameter of 0.35mm and the maximum length of 1850 mm. The above sizes can also be made according to user requirements.
