Base Tube Material: ASTM A269 TP304 Stainless Steel
ASTM A269 TP304 is an austenitic stainless steel that provides excellent resistance to corrosion, particularly in environments exposed to high temperatures or harsh chemicals. This makes it an ideal choice for air cooler tubes that need to withstand thermal stresses and corrosive elements. TP304 also offers good mechanical properties, making it durable in a variety of industrial applications.
Fin Material: A1060 Aluminum (Al1060)
The fin material used is A1060 aluminum, which is known for its excellent thermal conductivity, lightweight properties, and resistance to corrosion. The extruded fins provide an increased surface area for heat transfer, making this type of tube highly efficient in cooling applications.
Application: This tube is primarily used in air cooler systems, where it enhances the heat exchange performance, cooling air or fluids effectively. The combination of stainless steel for the tube and aluminum for the fins makes it well-suited for environments that require high heat transfer efficiency and corrosion resistance.
