In this study, the relationship between the drawing formability and texture of an Al–Mg–Si alloy with various rolling and heat treatment was investigated. The LDR (Limiting Drawing Ratio) value became highest only when the average r value was high and Δr was low. Randomization of texture by reducing the cube orientation density of the recrystallized texture is effective for improving draw formability. In order to obtain randomization of the final texture, it is important to randomize the initial orientation, to maintain proper solid solution and to form fine precipitates (clusters, acicular β″) in the middle of the process.
