Annealed Steel Wire
Introduction
It is called wire (from the Latin aerāmen, -ĭnis «bronze») generically to any flexible filament made of some metal.[1] It is usually formed by drawing the metal wire through a hole in a die "Die (cutting)") or drawing plate"), taking advantage of the property of "ductility" - a characteristic inherent to metals -. The main elements for the production of wire are: iron, copper, brass, silver, aluminum, among others. However, copper and its bronze and brass alloys were formerly called wire.[2] Wire gauges have various standard sizes, expressed in terms of gauge number or cross-sectional area.
Cables are used to support structural loads, often in the form of metal cables. In electricity and telecommunications signals, a "wire" can refer to an electrical cable, which may contain a "solid core" of a single wire or separate strands in twisted or braided forms.
Although its geometry is usually cylindrical, the wire can also have square, hexagonal, flattened rectangular or other sections, either for decorative or technical purposes, such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, like the toy Slinky, are made of special flattened wire.[2].
History
Wire has been used since many centuries before our era. In ancient times, jewelry often contained large amounts of wire in the form of chains and applied decoration that was precisely made and must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheets were made into wire by passing them through holes in stone beads. This causes the strips to fold back on themselves to form thin tubes. The oldest manufacturing procedure consisted of beating metal sheets to the required thickness, then cutting them into narrow strips that were rounded with hammer blows to turn them into wire. This procedure was applied until the middle of the century. However, in archaeological excavations, brass wires from more than 2,000 years ago have been found that, when examined, showed signs that their manufacture could be attributed to the "row (tool)" spinneret procedure. The metal that you want to convert into wire is first shaped into a bar, and then it is thinned and one of the ends of the bar is sharpened to pass it successively through the different holes in the row, from largest to smallest, until the metal bar is converted into wire of the desired thickness.
