Abstract

A continuous process for high speed fabrication of wire comprises the steps of directing wire through a first set of drawing dies to reduce the wire diameter to an intermediate diameter, applying a lubricant to the wire during the drawing process, annealing the intermediate diameter wire while it is still coated with some of the lubricant, controlling the tensile forces and elongation of the wire during the anneal, and drawing the annealed intermediate diameter wire to a desired final diameter in a second set of dies. The process is particularly well suited for fabricating fine copper wire having improved mechanical properties.
