Material: Base Tube - ASME SA-179 Carbon Steel | Fins - Aluminum 1100/3003
Extruded finned tubes combine the superior pressure resistance of carbon steel with the exceptional thermal conductivity of aluminum fins. Through a cold extrusion process, fins are metallurgically bonded to the base tube, creating a seamless heat transfer surface ideal for high-corrosion and high-temperature applications.
