Knowledge about extruded aluminum tubing
Extruded aluminum tubing as a high-strength hard aluminum, can be used for heat treatment hardening, in the annealing, quenching and thermal state of plasticity, spot welding is good, with gas welding and argon arc welding extruded aluminum tubing has a tendency to form intergranular crack; The extruded aluminum tubing has good machinability after quenching and cold hardening, and is poor in annealing condition. Corrosion resistance is not high, often using anodic oxidation treatment and painting methods or surface cladding aluminum layer to improve corrosion resistance.
Extruded aluminum tubing can also be used as mold material.
Advantages of extruded aluminum tubing:
First, welding technology advantages: Suitable for industrial production of thin-walled copper- extruded aluminum tubing welding technology, known as a world-class problem, is the air conditioner connecting the aluminum generation of copper key technology.
Second, the use of life advantages: from the a extruded aluminum tubing wall, because the refrigerant does not contain moisture, copper and extruded aluminum tubing wall will not occur corrosion.
Third, energy-saving advantages: Air conditioner indoor and outdoor machine connection pipe, heat transfer efficiency lower the more energy-saving, or, the better the heat insulation effect of electricity.
Four is good bending performance, easy to install, move machine.
extruded aluminum tubing is widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, home and so on, aluminum tube in our lives are everywhere。
