The ASME SA209 Embedded Fin Tube with Aluminum 1060 Fin is a specialized heat exchanger component designed for enhanced thermal conductivity and efficient heat transfer. This type of tube is commonly used in industrial applications where heat exchange plays a critical role in system performance, such as in power plants, HVAC systems, and chemical processing industries. The combination of ASME SA209 tubing material and aluminum 1060 fins makes it a high-performance solution for demanding environments.
ASME SA209 refers to a standard set by the American Society of Mechanical Engineers (ASME) for seamless ferritic alloy steel tubes used in heat exchanger and boiler applications. The SA209 specification is often used for tubes that are subjected to high-temperature environments and are typically used in boilers and superheaters. These tubes are known for their excellent resistance to high-pressure conditions, corrosion, and extreme temperatures, making them ideal for industrial heating systems.
An embedded fin tube is a type of heat exchanger tube where the fins (typically made of metals like aluminum) are mechanically attached or embedded into the surface of the tube. This embedding improves the surface area of the tube, which in turn increases the efficiency of heat transfer between the fluid inside the tube and the surrounding environment. The fins create a larger surface area for heat exchange, allowing the system to dissipate or absorb more heat, depending on the application.
Embedded fin tubes are designed for systems where compactness and high thermal efficiency are essential, and they are often used in air-cooled and water-cooled applications. The fins can either be spiral or straight, depending on the design requirements.

The fin material used in this design is Aluminum 1060, a highly pure form of aluminum known for its excellent thermal conductivity, corrosion resistance, and lightweight properties. Aluminum 1060 has a high purity level (typically around 99.6% pure aluminum) which enhances its heat transfer efficiency compared to other alloys.
In heat exchanger applications, Aluminum 1060 fins are advantageous due to their:
① High Thermal Conductivity: Aluminum is an excellent conductor of heat, making it ideal for applications where rapid heat transfer is required.
② Lightweight: The low density of aluminum makes it easier to handle and reduces the overall weight of the heat exchanger system.
③ Corrosion Resistance: Aluminum 1060 has a natural oxide layer that protects it from corrosion, which is particularly beneficial in humid or high-moisture environments.
④ Cost-Effectiveness: Compared to other materials, aluminum is relatively cost-effective, offering a balance between performance and affordability.
Base Tube:ASME SA209 vs. ASME SA106 Gr.B:
ASME SA209 base tubes (alloy steel) have better high-temperature strength, oxidation resistance, and creep resistance (suitable for ≤480℃) than SA106 Gr.B (carbon steel, ≤400℃). The former is ideal for medium-high temperature heat recovery (e.g., boiler flue gas, metallurgical waste heat), while the latter fits low-cost, medium-low temperature general heat exchange.
Fin:Al1060 vs. Cu-T2 :
Aluminum 1060 fins offer 30-40% cost advantage over Cu-T2 fins, with slightly lower thermal conductivity (237W/(m·K) vs. 390W/(m·K)). Al1060 is more cost-effective for general medium-high temperature heat exchange, while Cu-T2 suits high-efficiency low-temperature difference scenarios (e.g., precision process cooling).
