Our Copper Fin Tubes are manufactured from high-conductivity Cu-DHP copper, offering outstanding thermal conductivity, excellent corrosion resistance, and reliable performance under extreme operating conditions. Depending on the heat exchanger design and application, we supply tubes with integral (low) fins, extruded high fins, or wound L-type, KL-type, and G-type (embedded) fin profiles — each suited to different thermal-efficiency, cost, and durability requirements.
Copper Fin Tubes are the preferred choice wherever compact heat-transfer surfaces and consistent thermal performance are required — from HVAC cooling coils and marine condensers to process-industry heat exchangers and boiler heat-recovery systems. Every tube is produced with tightly controlled dimensions, fin density, wall thickness, and material properties to applicable ASTM standards, and is 100% eddy current and hydrostatically tested before dispatch.
As a renowned Copper Fin Tubes manufacturer and supplier in India, Amardeep Steel Centre supplies precision-engineered finned tubes with EN 10204 3.1 Mill Test Certificates to HVAC, marine, process, and industrial customers across India and for export worldwide.

Request a QuoteFin Type Comparison: Integral vs. Extruded vs. L vs. KL vs. G
- Integral (Low) Fin: Fins formed directly from the base tube wall by cold-working; highest mechanical bond to the tube, best for general-purpose HVAC and refrigeration heat exchangers.
- Extruded Fin: Fins extruded from an integral starting wall, giving taller, more efficient fins than standard integral finning; used where higher heat-transfer area per unit length is needed.
- L-Type Fin: An aluminium or copper fin strip wrapped and tension-wound onto the base tube under an L-shaped foot; cost-effective and widely used in air-cooled condensers and evaporator coils.
- KL-Type Fin: A reinforced version of the L-type fin with the foot wrapped and locked under tension for better fin-to-tube contact and higher operating temperatures than standard L-type.
- G-Type (Embedded) Fin: The fin strip is embedded into a pre-cut helical groove on the tube surface, giving the strongest mechanical and thermal bond of the wound-fin types; suited to higher-temperature and higher-vibration service.
Copper Fin Tube vs. Aluminium Fin Tube — Which to Choose
Parameter | Copper Fin Tube | Aluminium Fin Tube |
|---|---|---|
Thermal conductivity | ~339 W/m·K — higher, more efficient heat transfer | ~205 W/m·K — lower than copper |
Corrosion resistance | Excellent in most industrial, marine, and HVAC environments | Good, but more prone to galvanic corrosion in humid/marine air without coating |
Cost | Higher raw-material cost than aluminium | Lower material cost, often preferred for high-volume HVAC |
Weight | Heavier per unit length | Significantly lighter |
Typical use case | Marine, process, industrial, and high-reliability HVAC applications | Residential/commercial air conditioning where weight and cost dominate |
Fin Density (FPI) Options We Manufacture
- 19–24 FPI: lower fin density, used where airflow resistance must stay low (e.g. natural-draft condensers).
- 25–32 FPI: standard mid-range density for most HVAC and refrigeration coils.
- 33–40 FPI: higher fin density for compact, high-efficiency heat exchangers where surface area per unit length is the priority.
Copper Fin Tube Manufacturing Process
- Base tube drawing: seamless Cu-DHP (C12200) tube drawn to the specified OD and wall thickness per ASTM B111.
- Fin forming: fins are formed (integral/extruded) or wound and locked (L/KL/G type) onto the base tube to the specified FPI.
- Sizing & straightening: finned tubes are sized and straightened to the required straight length or prepared for U-bending.
- Testing: 100% eddy current testing and hydrostatic testing per ASTM B359 acceptance criteria.
- Certification & packing: EN 10204 3.1 Mill Test Certificates issued; tubes packed for domestic dispatch or export.

Frequently Asked Questions
What are Copper Fin Tubes?
Copper Fin Tubes are copper tubes with fins attached or formed on the tube surface to increase the heat-transfer area and improve thermal performance.
What are Copper Fin Tubes used for?
They are used in heat exchangers, HVAC systems, refrigeration equipment, condensers, evaporators, chillers, and other heat-transfer applications.
How do Copper Fin Tubes improve heat transfer?
The fins increase the surface area available for heat exchange, allowing heat to transfer more efficiently than through a bare tube.
Are Copper Fin Tubes suitable for heat exchangers?
Yes. They provide good thermal conductivity and increased surface area, making them suitable for various heat exchanger applications.
What is the difference between Copper Fin Tubes and bare copper tubes?
Copper Fin Tubes have fins that increase the heat-transfer surface area, while bare copper tubes have a smooth surface and provide less area for heat transfer.
Are Copper Fin Tubes suitable for condensers and evaporators?
Yes. Copper Fin Tubes are commonly used in condensers and evaporators because of their good thermal conductivity and efficient heat-transfer performance.
What is the difference between Integral and Extruded copper fin tubes?
Integral fins are formed from the base tube wall itself, while extruded fins are drawn taller from an integral starting wall for greater heat-transfer area per unit length.
Is copper or aluminium better for finned tubes?
Copper offers higher thermal conductivity and better corrosion resistance, making it preferred for marine, process, and high-reliability applications, while aluminium is lighter and lower-cost for standard HVAC use.
What fin density (FPI) should I choose for my application?
Lower FPI (19–24) suits natural-draft or low-airflow systems; mid-range (25–32) covers most HVAC/refrigeration coils; higher FPI (33–40) suits compact, high-efficiency exchangers.
Do you provide Mill Test Certificates with Copper Fin Tubes?
Yes, every batch is supplied with EN 10204 3.1 Mill Test Certificates after 100% eddy current and hydrostatic testing.
