High Thermal Alumina Corundum Tube

Corundum Tube：High Thermal Alumina Corundum  Tube   Affordable Corundum Tubes   Alumina ceramics exhibit excellent properties across a wide range of industrial and operating conditions. Heat-resistant corundum ceramic insulators/alumina tubes for electric furnaces are primarily used in heat treatment, protective tubes, insulation tubes, furnace tubes, radiant tubes, electric heater support tubes, beams, profiles, incineration aids, and specialty manufacturing.   Alumina ceramics offer excellent insulation, heat resistance, low thermal expansion coefficient, high thermal conductivity, high mechanical strength, good thermal conductivity, and chemical resistance. They are also non-flammable, rust-resistant, durable, and damage-resistant.   Advantages of High temperature alumina ceramic corundum tube：    1. Good smooth and high strength.    2. Extreme hardness, good protection from abrasion and corrosion.    3. High temperature resistance up to 1800℃.    4. High dielectric properties. …
