ABSTRACT:
This invention relates to a process for producing aluminum-containing strip stock which is suitable for drawing and ironing and has reduced earing. A continuously-cast, aluminum-containing strip is introduced into a hot-mill operation to provide a thickness reduction of at least 70 percent with the exit temperature of the strip being minimized. The strip is allowed to crystallize to form grain having an annealed texture. This strip is then subjected to cold rolling to reduce the thickness at least 30 percent. The cold-rolled strip is annealed at an intermediate annealing temperature. The annealed strip is then subjected to further cold rolling sufficient to optimize the balance between the 45.degree. earing and yield strength.
