  • Process for the fabrication of aluminum alloy sheet having high formability
    Patent number: 5690758
    Abstract: The invention relates to a fabrication process to obtain aluminum alloy sheet having high formability. In this process, an alloy obtained by alloying Al with Si, Mg, Cu, Mn and Fe, and one or more elements taken from the group of Cr, Zn, Zr and Ti, is subjected to a continuous solution treatment for at least 3 seconds at a temperature higher than 450.degree. C., followed by cooling to a temperature between 60.degree. and 250.degree. C., at a rate higher than 100.degree. C./min, followed by a coiling at the same temperature in the 60.degree. C.-250.degree. C. range and a preaging between 1 minute and 10 hours at the same cooling temperature of 60.degree. to 250.degree. C.
