PROBLEM TO BE SOLVED: To provide a rolling stock having strength, bending workability and corrosion resistance required as those for a coating material by utilizing brazing sheet scrap as the raw material, and to provide a method for producing the same at a low cost. SOLUTION: The ingot of an aluminum alloy using brazing sheet scrap as the raw material and having a composition comprising 1.0 to 3.2% Si and 0.1 to 1.2% Mn, and in which the content of Fe is controlled to≤0.7%, Mg to≤0.5%, Cu to≤0.6% and Zn to≤1.2% is subjected to homogenizing treatment in the temperature range of 450 to 570°C for 1 to 24 hr. Next, hot rolling is started at≥400°C and is finished at≤350°C, and further, cold rolling is performed at a rolling ratio of≥65%. COPYRIGHT: (C)2005,JPO&NCIPI
