Core Performance Advantages of Aluminum Tube Coil
Due to its multiple performance advantages, aluminum tube coil has become an ideal alternative to copper and stainless steel tubes in heat transfer systems and fluid transportation. The following is an overview of its main advantages:
-
Lightweight & Strong
Aluminum has only 1/3 the density of copper and boasts excellent specific strength, making it particularly suitable for lightweight equipment and structural optimization design scenarios, such as thermal management systems for new energy vehicles.
-
Excellent Thermal Conductivity
Common alloys such as 1060, 3003, and 6063 have good thermal conductivity, which can significantly improve system thermal efficiency and are widely used in heat exchanger modules such as air conditioners, condensers, and evaporators.
-
Superior Corrosion Resistance
The surface of aluminum can naturally form a dense oxide film. Combined with treatments such as anodizing, spraying, and galvanizing, it can operate for a long time in salt spray, high humidity, and light chemical environments.
-
Excellent Fabricability
Supports various processing methods such as cold bending, expansion, welding, cutting, and flaring, adapting to on-site assembly and automated production lines, facilitating efficient construction and system integration.
-
Structural Flexibility & Coiling Design
Compared to fixed-length straight tubes, aluminum tube coils are easier to transport and lay out, especially suitable for applications with limited space or requiring long-distance continuous laying, such as air conditioning refrigerant circuits and medical gas supply systems.

FAQs
What customized parameters can your aluminum tube coils support?
Chalco supports comprehensive customization of aluminum tube coils, including outer diameter (Ø3.5mm–28mm), wall thickness (0.3–1.5mm), length (1–50 meters), number of turns, and coil inner diameter (coil diameter). Among these, the coil diameter can be precisely matched according to the customer's coiling equipment or automatic feeding system to ensure perfect compatibility with your process flow.
Do you provide seamless aluminum tube coils? What is the difference between seamless and welded tubes?
Yes, Chalco primarily provides seamless aluminum tube coils, integrally formed by extrusion or cold drawing processes, avoiding the risk of weld leakage and offering higher pressure resistance and service life. In comparison, welded coils, although slightly lower in cost, have insufficient stability in high-temperature, high-pressure, or corrosive environments.
Are aluminum tube coils prone to cracking during use?
All Chalco aluminum tube coils undergo multiple annealing and forming controls, possessing good bending performance and toughness, suitable for repeated winding, straightening, and flanging. Within the normal cold bending radius range, the coils will not exhibit stress cracks or fractures. For strict bending radius requirements, we can adjust the alloy temper and annealing parameters accordingly.
Can aluminum tube coils replace copper tube coils? How do they perform in actual use?
In most HVAC, heat pump systems, cold chain transportation, and general fluid transfer scenarios, aluminum tube coils are a cost-effective alternative. Although their heat transfer efficiency is slightly lower than that of copper tubes, their lightweight nature, low cost, and good corrosion resistance make them more advantageous in space optimization and large-scale piping.
However, for precision equipment requiring extremely high thermal conductivity, high pressure resistance, or long-term stability, such as large refrigeration compression systems and medical gas delivery systems, copper tubes still offer stronger adaptability.
Chalco also offers copper-plated aluminum tube coil solutions, combining the performance of both, for your evaluation and selection.
Can you provide aluminum tube coils with processing, such as punching, flaring, and cutting?
Of course. Chalco has complete secondary processing capabilities and can provide deep processing services such as cutting, punching, end capping, flaring, and bending according to drawings, and supports batch pre-assembled modular delivery, significantly reducing your process costs and production cycle.Quick Quote
