Thin Wall Copper Tubes

-- Steady & Reliable Manufacturer --

Lightweight Efficiency with High Precision

Thin wall copper tubes are the pinnacle of material efficiency, offering the structural benefits of copper with a significantly reduced weight and material cost. These tubes are engineered for applications where thermal conductivity is the priority and where weight savings are critical, such as in aerospace, high-end consumer electronics, and compact heat exchangers. At Zhejiang Jingliang, our thin-wall production line uses advanced "Planetary Rolling" and precision cold-drawing to achieve wall thicknesses as low as 0.2mm without compromising the tube's concentricity or pressure rating. This requires a level of metallurgical purity that prevents "pinholing" during the drawing process. We utilize high-purity C12200 copper to ensure that even with a reduced wall, the tube retains the ductility to be formed into complex shapes or expanded into heat exchanger fins with a perfect metal-to-metal contact.

The primary challenge of thin-wall tubing is maintaining "Burst Pressure" integrity. Our engineering team calculates the optimal balance between wall thickness and temper to ensure that these tubes meet the safety standards for modern refrigerants and industrial fluids. We offer these tubes in both "Hard" and "Soft Annealed" tempers. Hard-drawn thin-wall tubes are exceptionally rigid and lightweight, making them perfect for decorative architecture and precision instrumentation. Soft-annealed versions are used in the manufacturing of micro-channel heat exchangers and high-efficiency radiator cores. By reducing the amount of copper per meter, thin-wall tubing also represents a more environmentally sustainable option, reducing the carbon footprint associated with mining and transport while providing the exact performance required for high-tech thermal management.

Applications in Micro-Technology & HVAC

Thin wall copper tubes are essential for the production of High-Efficiency Heat Exchangers, particularly for the "Fins and Tubes" assemblies used in modern AC units where they maximize heat transfer while minimizing size. In the automotive sector, they are used for Oil Coolers and lightweight Radiator assemblies. The electronics industry uses them for Heat Pipes in laptops and game consoles to dissipate heat from powerful CPUs. They are also found in Medical Instruments and laboratory equipment where precision fluid delivery is needed. In the decorative and furniture sector, they are used for high-end lighting fixtures and lightweight structural frames. Additionally, they are used for Capillary Tubes in refrigeration control systems. Because of their light weight and high strength-to-weight ratio, they are also increasingly used in aerospace for non-critical fluid lines and thermal shielding.

Advantages of Thin-Wall Design

The most obvious advantage is "Cost Savings." Using less copper per meter reduces the material cost of the project significantly without sacrificing the thermal performance of the system. "Enhanced Heat Transfer" is another major benefit; a thinner wall provides less resistance to thermal energy, making the heat exchanger more efficient. "Weight Reduction" is critical for mobile applications like cars and planes, where every gram saved contributes to better fuel efficiency. Our thin-wall tubes also offer "Precision Workability"—their high ductility means they can be expanded into fins with lower force, reducing wear on your manufacturing machinery. Furthermore, the "Mirror-Smooth" internal bore ensures that even in very small diameters, the pressure drop remains low. Finally, despite their thinness, these tubes offer excellent "Fatigue Life" when our specialized grain-refinement techniques are applied during the drawing process.

Handling, Packaging, and Payment

Thin-wall tubing is delicate and requires specialized "Rigid Packaging" to prevent crushing during transport. We use thick-walled cardboard tubes or custom-made wooden crates with internal dividers to protect every length. Payment is typically T/T or L/C at sight. We offer "Just-In-Time" logistics for electronics and automotive manufacturers who need constant supply for high-speed assembly lines. Every batch includes a detailed Dimensional Inspection Report and a Mill Test Certificate. Our quality control team uses ultrasonic gauges to verify wall thickness uniformity across the entire length of the tube. We ship globally from Ningbo port, with a focus on protecting the material from "Physical Distortion" and "Surface Scratching" throughout the journey.

  • Q: Are thin-wall tubes strong enough for high-pressure refrigerants?
  • A: Yes, as long as the diameter-to-wall-thickness ratio is within engineering limits. For R410A, we can design thin-wall tubes that still maintain a 4:1 safety factor.
  • Q: Can you bend thin-wall tubes?
  • A: Yes, but they require precise internal support (like mandrels or springs) during bending to prevent kinking. We can provide the soft-annealed temper to make this easier.
  • Q: What is the thinnest wall you can produce?
  • A: Our standard capability goes down to 0.20mm, but for specialized micro-electronics, we can discuss custom-drawing down to 0.15mm.
