A. Alumina combines low thermal expansion, excellent thermal conductivity and high compressive strength to make these furnace tubes resistant to thermal shock.
B. Alumina tube models have higher dielectric properties and provide higher vacuum or protective atmosphere at extreme temperatures.

Extruded Alumina Ceramic Tube/Pipe


My factory looking for distributors.


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

Alumina Furnace Tube


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.
