Product Description:

 high Alumina Ceramic Tubes, 99.7 Al2O3


We mainly produce 90 -99.7% alumina tubes, rods and various industrial ceramic parts, which are mainly used in thermalcouple temperature, liquid steel continous temperature, various industrial furnace(containing vacuum furnace, carburizing furnace, wire furnace, atmosphere furnace etc), especially widely used in petrochemical, spinning, electric, instrumentation, mechanical workout, military project etc industry.


Alumina is the most cost effective and widely used material in the family of engineering ceramics. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. With an excellent combination of properties and an attractive price, it is no surprise that fine grain technical grade alumina has a very wide range of applications.
