  • Method for laminating aluminum for fine-grain applications
    Patent number: 11174541
    Abstract: The present invention describes an aluminum rolling method comprising a stage a) of hot rolling at an initial temperature ranging from 450 to 500° C. up to a final temperature ranging from 360 to 400° C., obtaining an aluminum sheet with a thickness between 8 and 12 mm; and a stage b) of cold rolling wherein rolling passes at a temperature ranging from 75 to 120° C. are intercalated with an intermediate sub-stage of heat treatment at a temperature ranging from 340 to 390° C., until obtaining an aluminum sheet with a final thickness between 0.3 and 1 mm. Another object of the invention is the rolled aluminum obtained from the method explained in the present application and its use in manufacturing containers for the cosmetic and perfume industry.
