Copper sheets recrystallized have the cubic texture {100}⟨001⟩, and this orientation becomes very sharp with increasing cold rolling reduction. This {100} orientation, however, injures the drawability of metal sheets, resulting in inferior drawability of copper sheets compared with that of other metal sheets. Cold rolled copper sheets, on the other hand, are expected to have good drawability, because they have the favourable orientation {100} for the drawability.<BR>The present experimental results obtained from Load Deep Drawing Test verify that the copper sheets as cold rolled can be drawn successfully. The drawability decreases with increasing rolling reduction in the range of low reduction, but increases with the increase in reduction in high reduction range over 70%, reaching L.D.R. of 2.5 at 95% reduction. It is concluded that the drawability of copper sheets as cold rolled can be improved by development of the orientation {110}.
