How to control the hardness of aluminum tubing?
It can also be used as a mold material.
Aluminum advantages: First, welding technology advantages: suitable for industrial production of thin-walled copper and aluminum pipe welding technology, known as the world-class problem, the key technology is the air conditioner connecting tube aluminum and copper.
Corrosion resistance is not high, and often painted by anodic oxidation treatment method or surface plus clad layer to improve corrosion resistance. It can also be used as a mold material.
Is a high-strength aluminum hard, can be heat strengthened, in the annealed, hardened and thermal state just moderate plasticity, good spot welding, gas welding and aluminum welding time has a tendency to crack is formed between the crystal; aluminum tubes after hardening and work hardening can be cutting is still good, bad in the annealed state.
