High Thermal Conductivity Custom Alumina Tubes for Heating Tube

High Thermal Conductivity Custom Alumina Tubes: Perfect for Heating Tube Applications

Looking for high-performance alumina tubes tailored for heating tube systems?

Our custom 95%/99% Al₂O₃ pink alumina tubes stand out with exceptional high thermal conductivity,

ensuring efficient heat transfer while delivering reliable electrical insulation—ideal for upgrading and

optimizing heating equipment in industrial, manufacturing, and thermal processing scenarios.

Core Advantages of Our High Thermal Conductivity Alumina Tubes for Heating Tubes
- High Thermal Conductivity: Optimized for heating tube systems, enabling rapid and
- uniform heat transfer to boost heating efficiency and reduce energy consumption.
- Dual Purity Options: 95% Al₂O₃ (cost-effective solution for general heating tube insulation needs)
- and 99% Al₂O₃ (premium high-performance grade for high-temperature heating scenarios and high-voltage applications).
- Custom-Made for Heating Tubes: Fully customizable diameter, length, wall thickness,
- and end designs to perfectly fit your specific heating tube models and installation requirements—no more mismatched components.
- Superior Electrical Insulation & Thermal Stability: Volume resistivity up to 10¹⁵Ω·cm for safe operation,
- paired with excellent resistance to high temperatures and thermal shocks—ideal for continuous heating tube work conditions.
- Wear & Corrosion Resistance: Resists abrasion, chemical corrosion, and oxidation, extending service life of
- heating tube components and reducing replacement costs.

Alumina ceramic tubes of application:

1.Industrial Furnaces: Thermocouple protection tubes, furnace tubes, inspection tubes, rollers.

2.Semiconductor & Electronics:Diffusion furnace tubes, insulating sleeves, vacuum chamber components. 

3.Mechanical & Wear Parts: Wear-resistant linings, guide tubes, nozzles, sealing rings. 

4.Energy & Environmental: Fuel cell components, sensor protection tubes, sampling tubes. 

5.Laboratory:Tube furnace tubes, laboratory glassware.

Industrial Ceramic Performance Specifications

Al₂O₃ Content (%)	70-75	85	95	99.7
Density (g/cm³)	3.0	3.4	3.7	3.9
Bending Strength (MPa)	85	300	364	450
Coefficient of Thermal Expansion (200℃-800℃)	6	7	7.6	8
Thermal Conductivity (W/(m·K))	17	18	20	35
Dielectric Strength (kV/mm)	9	10	11	12
Working Temperature (Long Term Use) (℃)	1300	1400	1600	1750
Water Absorption (%)	5	<0.2	<0.25	<0.1-0.2

Main advantage of the Alumina ceramic tubes:

1.Maximum tolerable temperature: 1600°C–1800°C,It does not soften or deform at high temperatures,

has a low coefficient of thermal expansion, and exhibits excellent thermal shock resistance.

Alumina ceramic tubes of Feature:

1.High Temperature Resistance: Can be used for extended periods at temperatures up to 1600°C or even higher (depending on alumina purity, such as 99% alumina).

2.High Hardness and Wear Resistance: With a Mohs hardness of up to 9, second only to diamond, it effectively resists particle abrasion and erosion.

3.Excellent Electrical Insulation: Maintains good insulation performance even at high temperatures, making it an ideal material for insulating sleeves.

4.Chemical Corrosion Resistance: Excellent resistance to most acids, alkalis, salts, and molten metals (except for hydrofluoric acid and high-temperature corrosion from strong alkalis).

5.High Mechanical Strength: High compressive and flexural strength, but is a brittle material with poor resistance to mechanical impact.

6.Low Coefficient of Thermal Expansion: Good dimensional stability and relatively good thermal shock resistance (but not as good as zirconium oxide).

7.Bio-Inert: High-purity alumina is harmless to human tissue.
