High magnesium aluminum alloy state rolling preparation process

The invention discloses a high magnesium aluminum alloy state rolling preparation process, which relates to the technical field of aluminum alloy processing and aims to solve the problems that the thickness and the width of a plate are limited, a large tensile force stretcher is required for tensile reinforcement, the processing procedures are multiple and the like in the conventional high magnesium aluminum alloy processing and hardening mode. The invention does not need cold rolling, has small limitation on thickness and width, does not need drawing processing reinforcement, can simplify the production process, saves the cost and improves the production efficiency; the performance of the rolled plate is directly controlled by hot rolling, the plate can be a hot rolling structure, the production process is simpler and more efficient, and the high-magnesium aluminum alloy plate with good mechanical property and corrosion resistance is obtained.
