Fine Grinding Precision 1mm 2mm 3mm Small Diameter Al2O3 Ceramic Alumina Tube

Description of the ceramic alumina tube

Alumina ceramic tubes are found across a huge number of user industries due to cost-effective advantages and high-performance solutions. The combination of key properties makes them a go-to product in many different applications:

● High mechanical properties- Alumina work as various structural, engineering ceramic parts in machinery, equipment.

● Fully dense – Alumina (Al2O3) provides a non-permeable tube that protects from contamination and can be used to create a gas-tight assembly.

● Thermally stable – High purity alumina (Al2O3) can be used in both oxidizing and reducing atmospheres up to 1600°C (2910°F) and in vacuum furnaces up to 1750°C.
● High chemical resistance – Alumina is chemically inert and not corroded by water or steam. It offers good resistance to corrosive substances such as strong acids or alkalis, even at elevated temperatures.
● Electrical insulation – Alumina is also widely used as an electrically insulating material. It can be used for insulators operating at high temperatures (e.g. furnace lead-in tubes, fuel-cells)

We support numerous customized services to our clients as per their specific needs, like different materials, different shapes, different surface quality, different dimension accuracy.

Main characteristics of the ceramic alumina tube

1. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel

2. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.

3. Extraordinary electrical insulation, it always us in many high voltage, high-current application

4. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

5. Chemical corrosion resistance under high temperature, even if with strong acid or alkali

6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.

7. Low material cost in high-level applications than other technical ceramics
