How to control the hardness of aluminum pipe?
Can also be used as a die material.Advantages of aluminum tube: first, welding technology advantages: it is suitable for industrial production of thin-walled copper aluminum tube welding technology. It is called world class difficult problem, and it is the key technology of aluminum alloy for air conditioner connecting tube.
The corrosion resistance is not high, in order to improve the corrosion resistance of anodic oxidation treatment and often used methods of paint or aluminum surface layer.
As a kind of high strength aluminum alloy, heat treatment can be strengthened, annealing, quenching and heat under the condition of rigid plasticity, good welding, gas welding and argon arc welding in aluminum has the tendency of intergranular crack formation; aluminum hardening in quenching and cold cutting performance is good and bad in annealing state when.
