Alumina ceramic heater sleeve It is widely used in aerospace, automotive, electrical, electronic, power generation and other industries, such as industrial heating tubes, household appliances, electric heating rods and other equipment.
Extreme Temperature Resistance: Alumina ceramics can withstand operating temperatures up to 1600°C - 1750°C (2912°F - 3182°F), making them ideal for high-heat processes.
Excellent Electrical Insulation: Even at high temperatures, alumina remains an excellent electrical insulator. This is crucial for safely containing the internal heating element and preventing short circuits.
High Thermal Conductivity: For a ceramic, alumina has good thermal conductivity. This allows heat to transfer efficiently from the internal element to the outer surface of the sleeve and then to the object being heated, ensuring uniform temperature distribution.
High Mechanical Strength: It has high compressive strength, allowing it to maintain its shape and integrity under thermal expansion and mechanical load.
Chemical Inertness and Corrosion Resistance: Resists attack by fluxes, molten metals (like aluminum, zinc), and many corrosive gases, ensuring a long service life in harsh environments.
Electrical Insulation: It provides excellent electrical isolation, which is critical for safety and proper functioning.
