A. Alumina ceramic tube has good thermal stability, corrosion resistance, air tightness, thermal shock resistance and other properties.
B. It is widely used for the support, threading and insulation of various industrial furnaces.
My factory looking for distributors.
Size 6x4x200mm alumina ceramic tube
With good thermostability,corrosion resistence,air tightness,thermal shock resistance etc properties,ceramic tubes are widely used in various industrial furnace for supporting,threading and insulation etc purpose.
Holes drilling,slotting and grinding etc processing to ceramic tubes(OBE&COE)could achieve the ventilating,wire winding etc specific assembly requirement.
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.
We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.
6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.
Alumina Tubes as a standard ceramic product. Alumina can take temperatures up to 1800°C, having extremely high temperature stability, chemical corrosion resistance, and high wear and abrasion resistance. Most items are in stock and can be pulled and shipped normally under 1 week ARO. Smaller diameter tubes are produced by extrusion, while larger diameters are produced by casting. Sizes are available from .031" OD to 4.72" OD . please contact us and we will be happy to quote your custom size.
