    摘要： An aluminum alloy finstock of lower (more negative) corrosion potential and higher thermal conductivity than its elemental composition would normally provide is produced by a specific process. The process comprises continuously strip casting the alloy to form a strip, optionally hot rolling the strip to an intermediate gauge sheet, annealing the sheet and cold rolling the sheet to final gauge. The 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 °C/second, e.g. by conducting the casting step in a twin-roll caster.

    摘要： A method of producing an aluminum alloy finstock 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 of the indicated composition, preferably produced by the method, which has good thermal conductivity, and is suitable for use in thin gauge (e.g. less than 100 νm, and preferably 60 ± 10 νm).

    摘要： An aluminum alloy foil is formed from an alloy containing about 1.2 to 1.7% by weight iron, about 0.4 to 0.8% by weight silicon and about 0.07 to 0.20% by weight manganese, with the balance aluminum and incidental impurities. The alloy is continuously strip cast, e.g. on a belt caster, to form a strip having a thickness of less than about 25 mm, which is then cold rolled to interanneal gauge followed by interannealing at a temperature of about 280 to 350 DEG C. The interanneal strip is cold rolled to final gauge and further annealed to form the final foil product, having high strength and excellent quality.
