Abstract

The invention provides a processing technology of a 50mm thick aluminum alloy panel for a ship. The processing technology is characterized by comprising the following step of sequentially carrying out face-milling, heating, rolling, shearing, stretch flattening and sawing and sizing on a 5083 aluminum alloy cast ingot to obtain the aluminum alloy panel for the ship. According to the processing technology of the aluminum alloy panel provided by the invention, a hot rough rolling step is combined with the heating, shearing and stretch flattening steps and the like, so that the mechanical performance and the resistance to corrosion of the aluminum alloy panel in an H116 state can be enhanced.
