<p>A process for the production of a base foil of an aluminum alloy is provided which comprises a first heating step in which a cold-rolled plate derived from a continuously cast-rolled plate is maintained at a temperature between higher than 350 °C and lower than 450 °C for longer than 0.5 hour, the cast-rolled plate being comprised of a Al-Fe-Si type aluminum alloy, the aluminum alloy containing Fe in a content between more than 0.3 % by weight and less than 1.2 % by weight and Si in a content between more than 0.20 % by weight and less than 1 % by weight and having a Si/Fe ratio between above 0.4 and below 1.2, and a second heating step in which the resultant plate is maintained at a temperature between higher than 200 °C and lower than 330 °C for longer than 0.5 hour. The base foil is substantially free of macroscopic and microscopic rib patterns on its rolled and mat surfaces.</p> |
