Our alumina ceramic tubes are exported to more than 30 countries. The quality of our products is deeply liked by customers. Crucible products are also purchased by many university laboratories and mining laboratories. Parts products are also ordered by many large machine companies.

 

                                    Extruded Alumina Ceramic Tube/Pipe



Minerals containing alumina make up nearly 15% of the earth’s crust making it practically inexhaustible and versatile. Alumina combines low thermal expansion, superior thermal conductivity, and high-compressive strength to make these furnace tubes thermal-shock resistant. alumina tube models come with elevated dielectric properties and offer a higher vacuum or protective atmosphere at an extreme temperature.


All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680

Ceramic


Our alumina tubes offer:

 --
Extreme high temperature stability under reducing, inert, and high-vacuum condition under high temperature up to 1800°C.
 --Extreme wear and abrasion resistance.
 --Chemical corrosion resistance under high temperature.
 --High dielectric properties.
 --Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
