Wear and Corrssion Resistant Alumina Tubes Ceramic Bar

Alumina tubes are high-performance ceramic components made from aluminum oxide (Al₂O₃), a material known for its exceptional hardness, thermal stability, and chemical resistance. These tubes are widely used in industries requiring extreme durability, high-temperature resistance, and protection against wear and corrosion.

Key Properties of Alumina Tubes

High-Temperature Resistance – With a maximum operating temperature of up to 1600°C, alumina tubes are ideal for furnace linings, thermocouple protection, and molten metal handling.

Exceptional Wear Resistance – Due to their high hardness (≥1500 HV), they outperform metals and plastics in abrasive environments like mining and cement industries.

Corrosion Resistance – Alumina is inert to most acids, alkalis, and solvents, making it perfect for chemical processing and semiconductor applications.

Electrical Insulation – With high dielectric strength (15–20 kV/mm), alumina tubes are used in electronics and high-voltage applications.

Mechanical Strength – They offer excellent flexural strength (300–400 MPa) and structural stability under mechanical stress.

Alumina tubes come in various purity levels (96%–99.9% Al₂O₃) and can be customized in diameter (2mm–200mm), length, and surface finish (polished, machined, or as-fired).

Conclusion

Alumina tubes are essential in industries where extreme conditions demand long-lasting, non-reactive, and thermally stable materials. Their versatility makes them a preferred choice for engineers and manufacturers worldwide.

﹡Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
