A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

METHODS OF PRODUCING 6XXX SERIES ALUMINUM ALLOYS AT THIN GAUGE
Provided herein are highly-formable aluminum alloys and methods of making such alloys. The method of preparing aluminum alloys described herein can include a cold work thickness reduction subsequent to a solution heat treatment step to produce an aluminum alloy product exhibiting improved formability.

Reducing the number of passes to produce an aluminum alloy product with a desirable gauge can reduce carbon emissions and energy consumption associated with producing the aluminum alloy product.
