The orientation characteristics of a pure iron tape fabricated by cold rolling and annealing were evaluated using electron backscatter diffraction (EBSD) analysis. The {1 7 1}<4 $\bar{3}$ 17> orientation, which is a near-cube orientation, was strongly formed on the tape surface. For the oriented iron tape, the out-of-plane misorientation of (0 0 1) from the cube orientation is ca. 11°. The areal fraction of cube orientations with an angular deviation ≤20° amounts to 94.7%. The average grain size is approximately 370 μm for the near-cube oriented iron tape.
