High-Strength Alumina Ceramic Tubes Industrial Core Components For High-Temperature Applications
Product Overview

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.

Main Applications
  • 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
Product Advantages
  1. High-temperature resistance: Maximum service temperature up to 1650°C
  2. High hardness: Rockwell hardness HRA ≥ 85
  3. Excellent insulation: Volume resistivity > 10¹⁴ Ω*cm
  4. Corrosion resistance: Withstands most acids and alkalis
  5. Superior wear resistance: Service life exceeding metal components by 10 times
