1. What is ASTM A213 TP316L Solid Fin Tube with Aluminum 1060?
The ASTM A213 TP316L Solid Fin Tube with Aluminum 1060 is a premium heat transfer solution engineered for extreme corrosion resistance and high thermal efficiency. It features a seamless low-carbon stainless steel base tube (ASTM A213 TP316L, 16-18% Cr, 10-14% Ni, 2-3% Mo) integrated with solid Aluminum 1060 fins (99.6% pure Al) through an advanced extrusion process. The fins are mechanically bonded to the tube surface, forming a seamless, monolithic structure that eliminates air gaps and maximizes heat transfer. Ideal for hygienic and aggressive environments, this design combines TP316L’s chloride resistance with Aluminum 1060’s ultra-high conductivity (235 W/m·K), delivering unmatched durability and performance.
