Characteristics: it is a kind of high-strength duralumin, which can be reinforced by heat treatment, has medium plasticity in annealing, hardening and thermal state, good spot welding, and tends to form intercrystalline cracks in aluminum pipe when it is used in gas welding and argon arc welding.The machinability of aluminum tube is good after quenching and cold working hardening, but not good in annealing state.Corrosion resistance is not high, often use anodic oxidation and coating method or the surface coated with aluminum layer to improve the corrosion resistance.It can also be used as a mold material.
Advantages of 2024 seamless aluminum tube:
First, welding technology advantages: suitable for industrial production of thin - walled copper - aluminum tube welding technology, known as the problem, is the key technology of air conditioner connection tube aluminum instead of copper.
Second, the advantage of service life: from the inner wall of aluminum tube, because the refrigerant does not contain moisture, the inner wall of copper and aluminum connection tube will not corrode.
Three is the advantage of energy saving: air conditioner indoor and outdoor connection pipeline, the lower the heat transfer efficiency the more energy saving, or, the better the insulation effect the more energy saving.
Four is good bending performance, easy to install, transfer.
