Cold working refers to forming or forging metal at temperatures far below what is necessary for heat-treating. Cold working techniques are used to produce a variety of shapes and dimensions in metals, including bars, wire, tubes and sheets
In general, cold working involves heating the metal's surface area before forming or forging it into desired shapes. One of the most common applications of cold-working techniques is in making wire. In this application, a wire rod or bar is heated to its welding temperature (no higher than 400~C) so that it can be easily bent into any desired shape without breaking.
