Abstract
A method of producing an aluminum alloy fin stock material, comprising the steps of continuously strip casting an aluminum finstock alloy to form an as-cast strip, rolling the as-cast strip to form a sheet article of intermediate gauge, annealing the sheet article of intermediate gauge, and cold rolling the annealed sheet article of intermediate gauge to produce an aluminum finstock material of final gauge. The steps are carried out on a finstock alloy which comprises the following elements in weight percent: Fe 1.6 to 2.4; Si 0.7 to 1.1; Mn 0.3 to 0.6; Zn 0.3 to 2.0; Ti 0.005 to 0.040; incidental elements less than 0.05 each, total no more than 0.15; and the balance aluminum. The invention also relates to the finstock material so-produced which has good thermal conductivity, and is suitable for use in thin gauge (e.g. less than 100 .mu.m, and preferably 60.+-.10 .mu.m).
