Abstract: An improved aluminum alloy fin stock is described having both a high strength and a high thermal conductivity. The fin stock contains 1.2-1.8% Fe, 0.7-0.95% Si, 0.3-0.5% Mn, 0.3-1.2% Zn and the balance Al, and is produced by continuously strip casting the alloy at a cooling rate greater than 10null C./sec. but less than 200null C./sec., hot rolling the strip to a re-roll sheet without homogenization, cold rolling the re-roll sheet to an intermediate gauge, annealing the sheet and cold rolling the sheet to final gauge. This fin stock has a conductivity after brazing of greater than 49.8% IACS.
