What are the characteristics of aluminum?
Second, the advantages of life: from the inner wall of the tubes, due to moisture-free refrigerant, copper-aluminum connecting pipe wall corrosion does not occur.
Third, energy-saving advantages: air conditioner indoor unit and outdoor unit connecting pipe, the lower the heat transfer efficiency energy-saving, or rather, the more power the better the insulation effect.
Fourth, good bending performance, easy installation, transfer machines
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.
Aluminum features:
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 compared to aluminum welding time has a tendency to crack is formed between the crystal; aluminum tubes after hardening compared to work hardening can be cutting is still good, bad in the annealed state.
