Abstract
Provided is an Al—Mg alloy plate for molding, having excellent press formability, little stretcher strain (SS) mark generation, and not generating any new issues such as reduced bending properties as a result of age-hardening at room temperature, while using more accurate and simple structural indicators. As a result, the Al—Mg aluminum alloy plate comprising a specific composition including Cu has a plate structure having an average particle diameter of 0.5-6.0 nm in a minute particle (cluster) particle distribution measured using an X-ray scattering method, controls the volume fraction to at least 0.03%, is unlikely to have serration, and suppresses SS mark generation during press forming.
