Alumina ceramic tubes are advanced industrial ceramic products manufactured from high-purity aluminum oxide (Al₂O₃) as the primary raw material, sintered at temperatures exceeding 1700°C. They exhibit excellent mechanical strength, high hardness, outstanding wear resistance, and stable chemical properties, maintaining reliable performance under harsh conditions including high temperatures and corrosive environments, making them ideal structural ceramic materials.
High-temperature kilns: Thermocouple protection tubes, furnace rollers
Electronics and electrical: Insulating sleeves, vacuum tube housings
Mechanical equipment: Wear-resistant liners, guide tubes
Chemical and metallurgical industries: Molten metal transfer pipes, anti-corrosion pipe linings
High-temperature resistance: Maximum service temperature up to 1650°C
