The ASTM A269 TP304 Extruded Finned Tube with Aluminum 1060 is a premium heat transfer solution designed for corrosive and high-purity applications. It combines a seamless austenitic stainless steel base tube (ASTM A269 TP304, 18% Cr, 8% Ni) with Aluminum 1060 fins (99.6% pure aluminum) through a precision extrusion process. The fins are mechanically bonded to the tube surface under controlled conditions, ensuring a seamless, gap-free interface. This hybrid design leverages the corrosion resistance of TP304 stainless steel in acidic/chloride environments and the ultra-high thermal conductivity of Aluminum 1060, making it ideal for industries requiring hygiene, durability, and rapid heat transfer.
