AB  - Anisotropic behavior is a key characteristic for understanding eccentricity in tubes. Inthis paper, the effect of using a tilted die during tube drawing on eccentricity, texture, dislocationdensity, and mechanical properties is shown. Copper tubes were drawn with a 5 tilted die fortwo passes. The increase or decrease in eccentricity can be controlled by controlling the angle ofthe tilted die. Two types of textures have been developed during tube drawing, namely planestrain and uniaxial types. Plain strain type texture is mainly characterized by the  fiber with adominant copper component 112<111>. The uniaxial deformation type is dominated by the <111>fiber, as commonly found by wire drawing. Texture sharpness increases with increasing drawingstrain, and the texture varies significantly between the maximum and minimum wall thickness.This texture variation between maximum and minimum wall thickness has no significant influenceon mechanical properties, which are more or less similar, but the increase in strength after eachdrawing pass is apparent. The dislocation density is low for the as-received tubes due to recovery andrecrystallization. This is consistent with the as-received texture dominated by the cube component001<100>. During tube drawing, dislocation density increases as a function of the deformationstrain. The variation of dislocation density between the maximum and minimum wall thicknessin the tube deformed with 􀀀5 tilted die is higher than the variation in the tube deformed with+5 tilted die.
