Share your base tube alloy, fin type and duty and we will confirm the right copper finned tube specification.
What Are Copper Finned Tubes?
Copper finned tubes are copper or copper alloy base tubes, manufactured to ASTM B111, with fins added to increase the external surface area available for heat transfer. The fin material is usually copper or aluminium strip, wound, wrapped or extruded onto the tube depending on the fin type specified.
Because copper conducts heat far better than steel, copper finned tubes remain the first choice wherever compact, high efficiency heat exchange is needed between a fluid inside the tube and air or gas outside it.

Applications of Copper Finned Tubes
- Air cooled heat exchangers built to API 661
- Marine and industrial condensers
- Chillers and refrigeration coils
- HVAC coils and process cooling equipment
Choosing the Right Copper Finned Tubes Alloy
DHP copper (C12200) is the standard choice for fresh water and general HVAC duty at moderate cost. For seawater, brackish water or marine atmosphere exposure, copper nickel alloys resist chloride pitting and biofouling far better than plain copper, with C71500 (70/30) recommended over C70600 (90/10) for the most aggressive services.
Testing and Certification for Copper Finned Tubes
- Eddy current test on the base tube
- Hydrostatic pressure test
- Chemical composition and mechanical property verification per ASTM B111
- Mill test certificate per EN 10204 3.1B

Copper Finned Tubes FAQs
Q. What is a copper finned tube used for?
Copper finned tubes give compact, efficient heat transfer between a fluid inside the tube and air or gas outside it, which is why they are the standard choice for air cooled heat exchangers, condensers, chillers and HVAC coils.
Q. What is the difference between L type and LL type fin?
L type fin wraps a single layer of fin strip around the base tube with the foot forming an L shaped cross section. LL type doubles that wrap to fully cover the base tube, which adds corrosion protection where the tube material is less resistant than the fin.
Q. Which copper alloy is best for marine condenser tubes?
Copper nickel alloys, C70600 (90/10) or C71500 (70/30), resist chloride corrosion and biofouling far better than DHP copper (C12200) and are the standard choice for seawater and marine condenser duty.
Q. What standard governs copper finned tube base tubes?
ASTM B111 (ASME SB111) governs the base tube. The finning operation is typically qualified against TEMA or the buyer's own technical delivery conditions.
