A high-performance new 6XXX aluminum alloy thin strip and a preparation method thereof, the aluminum alloy thin strip has the following composition mass percentages: Si 0.5-1.5%, Mg 0.1-2.0%, Fe 0.1-1.0%, Mn 0.05-0.5%, Cu 0.02～0.2%, Ti 0.01～0.08%, B 0.001～0.008%, the balance is Al and other unavoidable impurity elements, and the individual impurity content is less than or equal to 0.05%, and the total impurity content is less than or equal to 0.15%. Compared with the existing 6XXX aluminum alloy, the preparation method of the invention uses the 6XXX aluminum alloy thin strip cast and rolled by spray deposition combined with the twin-roll thin strip casting and rolling process. Easily achieve more than 50% lighter weight. The aluminum alloy thin strip of the invention can be widely used in the field of automobiles, such as automobile engine covers, fenders, doors, roofs and trunk lids, etc., and provides the automobile industry with advantages in lightening weight, reducing energy consumption and improving fuel economy. There is a lot of room for sex. |
