High Thermal Conductivity | Lightweight | OEM-Grade Reliability
Aluminum tubing coil is a key heat exchange material widely used in HVAC systems, heat pumps, automotive thermal management, refrigeration units, and cold chain cooling systems.
Compared with copper, it offers outstanding thermal efficiency, energy-saving performance, corrosion resistance, and lightweight structure, making it suitable for large-scale manufacturing and OEM supply.
Aluminum tube is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity under annealing, hardening and hot state, and good weldability in spot welding. Aluminum tube has a tendency to form intergranular cracks during gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve the corrosion resistance. Can also be used as a mold material.
Chemical treatment: oxidation, electrophoretic coating, fluorine carbon spraying, powder spraying, wood grain transfer
Mechanical treatment: mechanical drawing, mechanical polishing, sandblasting.
| Treatment | Method | Engineering Benefit |
|---|---|---|
| Chemical | anodizing · electrophoresis · powder coat · fluorocarbon · hydrophilic | corrosion resistance / enhanced heat transfer |
| Mechanical | sandblasting · brushing · polishing | smoother fit / bonding improvement |
| OEM-level | degreasing / anti-oxidation coating | brazing-friendly & assembly-ready |
✅ Excellent welding technology: suitable for industrial production of thin-wall copper aluminum pipe welding technology, known as a world-class problem, is the key technology of air conditioner connection pipe aluminum copper replacement.
✅ Longer service life: from the inner wall of the aluminum pipe, because the refrigerant does not contain moisture, the inner wall of the copper and aluminum connection pipe will not corrod.
✅ Energy saving: the connection pipeline between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy saving, or the better the heat insulation effect, the more power saving.
✅ Excellent bending performance, easy to install and move.
