In [], Kraft et al. reported the process of drawing a commercial electrolytic tough pitch copper (Cu-ETP) wire in an annealed condition at low speed with a drawing block.The authors showed that different die angles result in significant differences in the parameter ∆, strain rate, and total deformation strain (due to redundant strain).

The wire drawing process begins with the preparation of the wire rod, which is typically a thick, coiled wire. This preparation includes cleaning and lubricating the rod to ensure smooth drawing. The cleaning process might involve chemical or mechanical methods to remove any surface impurities, and the lubrication helps in reducing friction ...

Annealed copper goes through the same drawing process as hard-drawn copper but is heat-treated soon after as part of the manufacturing process. The heat makes annealed copper easier to work with, bend and shape, making for a "softer" and less brittle wire.

 — For copper wires an 8 mm copper rod (5/16″ in USA) is used as raw material, which, through drawing dies, is drawn to the required bare wire size in several stages.
