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.
