A metal material includes a metal having a body-centered cubic structure, in which with respect to a sum of orientation area fractions of a {001} plane, a {101} plane and a {111} plane, a ratio of the orientation area fraction of the {111} plane is 0.45 or more.

Multi-layer metal or pseudometallic materials having engineered anisotropy are disclosed. The multi-layer materials having defined engineered grain orientations in each layer of the multi-layer material and bond layers between adjacent layers orthogonal to the grain orientations. This configuration distributes applied stress across the plurality of layers in the multi-layer metal material and around a neutral axis of the multi-layer metal material and increases the overall mechanical properties of the disclosed multi-layer metal material relative to conventional wrought metal materials of the same or similar chemical constitution.
