Process for the production of aluminum alloy sheet with a high yield strength and proper ductibility, especially used in the manufacture of automotive panels. This process includes no heat treated aluminum alloy casting into a strand, then described through a series of continuous casting billet rolling the final specification sheet, a better choice is the subsequent heat treatment back recrystallization. Rolling step includes hot-rolled and the rolling slab to be intermediate thickness of the intermediate products and cooling products in the Middle, then at room temperature to 340 degrees Celsius temperature range which rolled and cold-rolled products are the ultimate size sheet in the middle. This series of rolling process is continuing without intermediate ring around the fully annealed and intermediate plate. The invention also relates to a sheet of alloy products.

ĦĦĦĦThe invention relates to the production of a production process of aluminum plate. In particular, the invention is produced by rolling from heat-treated alloy suitable for forming of sheet metal. For example, the 5000 series aluminum alloy in the manufacture of Auto Panel.

ĦĦĦĦ5000 series aluminum alloys (magnesium as the main alloying elements) commonly used in automobile Panel (trim, doors, hood, and so on), for this application, providing alloy plate with high yield and high ductility desired. Appropriate specifications and yield strength of aluminum alloy by continuous casting roll received. In the traditional continuous casting process, casting of metals after hot rolling and temperature, and then coiled (at temperatures around 300 degrees Celsius) is then sent to another mill, the temperature does not exceed 160 degrees Celsius last cold.

In order to refine, where mention of what is commonly referred to by the "hot" was implemented when the temperature is above the recrystallization temperature of the alloy. Path to alloy
