1. High Temperature Resistance: Alumina ceramics can withstand extremely high temperatures, often exceeding 1700°C, making them ideal for use in high-temperature environments like furnaces and kilns. 2. Excellent Wear Resistance: Due to their hardness, alumina ceramic tubes and pipes are highly resistant to abrasion, which extends their lifespan significantly in applications involving high wear. 3. Chemical Inertness: Alumina ceramics are chemically inert to most acids, alkalis, and solvents, making them suitable for use in corrosive environments without degrading. 4. Electrical Insulation: Alumina ceramics tubes have excellent electrical insulation properties, making them ideal for use in electrical and electronic applications where high insulation is required. 5. High Mechanical Strength: Alumina ceramics tubes have high compressive strength, which allows them to withstand mechanical stress and pressure in demanding applications. 6. Low Thermal Conductivity: Alumina ceramic tubes and pipes have low thermal conductivity, which makes them useful for applications that require thermal insulation.
