Anisotropy of mechanical properties in full annealed sheets was studied using pure aluminum with 100 001 . Yield stress anisotropy was not observed. However, work hardening behavior, flow stress and several kinds of elongation were different depending on tensile direction. The anisotropic behavior in fracture elongation was well consistent with that in uniform elongation. Namely, the elongation was maximum at a direction of 45°to RD. In contrast, elongation parallel to RD exhibited the minimum
