High-bending aluminum alloy plate and short-process preparation method thereof

The invention discloses a high-bending aluminum alloy plate and a short-process preparation method thereof. The high-bending aluminum alloy plate comprises the following components in percentage by mass: less than or equal to 0.25% of Si, less than or equal to 0.40% of Fe, less than or equal to 0.10% of Cu, less than or equal to 0.10% of Mn, 2.2-2.8% of Mg, 0.15-0.35% of Cr, less than or equal to 0.10% of Zn, 0.015-0.02% of Ti, 0.00008-0.00015% of Be and the balance of Al and inevitable impurities. By optimizing the components of the 5052-H32 aluminum alloy and adjusting the preparation process, subsequent cold rolling, annealing and other processes are omitted, the technological process is shortened, the production efficiency is improved, the production cost is reduced, the bending performance of the product is improved, and the problems that in the prior art, the technological process is long, and cracking is likely to happen during bending forming are solved. 本发明公开了一种高折弯铝合金板材及其短流程制备方法，包括按质量百分比计的如下成分：Si≤0.2
