Diameter 10mm alumina insulating tube

Productive  Technology:   Alumina ceramic is the special corundum ceramic that been sintered under 1800 °C with the     main raw material of Al2O3 and flux of rare metal oxide.Using the high strength organic/inorganic    bond to felt together, and then grinding to the size as drawing required.   Advantages:    1.High temperature    2.Good insulation    3.High strength    4.Precision Process
