Abstract
An aluminum alloy fin stock of lower (more negative) corrosion potential and higher thermal conductivity is produced by a process, which comprises continuously strip casting the alloy to form a strip, cold rolling the strip to an intermediate gauge sheet, annealing the sheet and cold rolling the sheet to final gauge. Lower corrosion potential and higher thermal conductivity are imparted by carrying out the continuous strip casting while cooling the alloy at a rate of at least 300.degree. C./second, e.g. by conducting the casting step in a twin-roll caster.
