Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina ceramic is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has moderate plasticity in annealing, quenching and hot state. It has good spot welding and good tendency to form intergranular cracks in aluminum tubes during gas welding and argon arc welding. The aluminum tube has good cutting performance after quenching and cold work hardening, and is poor in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance. It can also be used as a mold material. Advantages of aluminum tube: First, the advantages of welding technology: thin-wall copper-aluminum tube welding technology suitable for industrial production, is the key technology of aluminum-based copper for air conditioner connection tube. Second, the service life advantage: from the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube does not corrode. The third is the energy-saving advantage: the connecting line between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy-saving, or the better the heat insulation effect, the more power-saving. Fourth, the bending performance is excellent and easy to install.
Chemical treatment: oxidation, electrophoretic coating, fluorocarbon coating, powder coating, wood grain transfer.
Mechanical treatment: mechanical drawing, mechanical polishing, sand blasting.
Alumina Ceramic Tubes are widely used in various industries, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home, etc. Aluminum tubes have become ubiquitous in our lives.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
