Abstract: An aluminum alloy material according to an embodiment of the present invention is an aluminum alloy including a grain boundary and a plurality of grains divided by the grain boundary, and having a face-centered cubic crystal structure, and includes a band formed by employing one or more non-metallic elements selected from oxygen (O), carbon (C) and nitrogen (N) in an aluminum matrix. Each of the grains includes a plurality of sub-grains divided by a low-angle grain boundary (LAGB), and a band positioned at the low-angle grain boundary may form a coherent interface with an aluminum matrix. Since a plurality of dislocations already are present in the band, a dislocation cell size is reduced during plastic deformation, which greatly contributes to an improvement in elongation. Such an aluminum alloy material can be subjected to cold rolling at a high reduction rate, and as a result, a plate having significantly improved elongation can be obtained.
