Specialized drawing
In drawing, material is stretched by passing it through dies at room temperature. Wires, rods, or pipes have sections reduced while the sectional shape -- cylindrical, hexagonal, square, or other -- is changed. Drawing requires cold drawing to ensure excellent inner and outer surface finishing not obtainable through hot-process finishing such as by hot rolling or hot extrusion. Extruded materials are often used for drawing, but drawn tubes and rods have higher dimensional accuracy than extruded materials.
