1. High Hardness: Alumina pipes are extremely hard, ranking 9 on the Mohs scale. This high hardness makes them highly resistant to abrasion, which is essential in applications involving high wear and tear. 2. Excellent Thermal Stability: With a melting point exceeding 1800°C, alumina pipes can withstand extreme temperatures without deformation or loss of structural integrity. This makes them suitable for high-temperature applications, including furnace linings and thermocouple protection tubes. 3. Corrosion Resistance:Alumina pipes is chemically inert and resists corrosion from acids, alkalis, and other harsh chemicals. This property is particularly beneficial in chemical processing industries where pipes are exposed to corrosive substances. 4. Electrical Insulation:Alumina pipes are excellent electrical insulators, which is why they are commonly used in electrical and electronic applications, such as insulators in high-voltage systems.
