Alumina Tube Applications

Our alumina tubes are essential components in demanding environments across industries:

• High-Temperature: Furnace tubes, thermal processing, thermocouple sheaths.
• Semiconductor: CVD, diffusion processes, and wafer manufacturing.
• Industrial: Insulators, injector tubes, and components for harsh chemical environments.
• Laboratory & R&D: Sample holders, tube furnaces, and custom prototypes.

Alumina Tube Packaging

Our products are packaged in customized cartons of various sizes based on the material dimensions. Small items are securely packed in PP boxes, while larger items are placed in custom wooden crates. We ensure strict adherence to packaging customization and the use of appropriate cushioning materials to provide optimal protection during transportation.

Packaging: Bottle, Carton, Wooden Box, or Customized.

Alumina Tube FAQs

1. What are alumina tubes' limits in resisting temperatures?

Aluminum oxide tubes typically possess a temperature resistance between 1400°C and 1750°C, depending on purity and manufacturing quality. High-purity tubes (99.7% and above) possess high thermal stability and are best applied to high-temperature applications like industrial furnaces and safeguarding thermocouples.

2. How chemically resistant and robust are Al2O3 tubes?

These tubes have very high mechanical strength, very good compressive and bending strength. They also have very good chemical resistance, being resistant to most alkalis and acids, and are more than adequate in providing endurance in harsh industrial environments.

3. Are your alumina tubes porous?

Yes, all of our alumina tubes are non-porous and dense. They are made by high-temperature sintering in order to offer maximum mechanical strength, chemical resistance, and gas-tight operation.
