Wire

History and Production of Wire

Jewelry in antiquity often contained wire in the form of chains and applied decoration.
Strips cut from metal sheet were made into wire by pulling them through perforations in stone beads.
Gold wires in jewelry from the 2nd millennium BCE have seam lines that follow a spiral path along the wire.
Square and hexagonal wires were possibly made using a swaging technique.
True beaded wire, produced by mechanically distorting a round-section wire, appeared in the Eastern Mediterranean and Italy in the 7th century BCE.
Wire is reduced to the desired diameter by repeated drawing through progressively smaller dies.
Annealing may be done to facilitate more drawing or to maximize ductility and conductivity.
Electrical wires are usually covered with insulating materials such as plastic or rubber-like polymers.
Coaxial cables can be formed by wrapping two or more wires concentrically, separated by insulation.
Wire or cable may be further protected with substances like paraffin, bitumen, or steel taping.

Solid wire, also called solid-core or single-strand wire, consists of one piece of metal wire.
Solid wire is useful for wiring breadboards.
Stranded wire is made up of multiple small wires twisted or braided together.
Stranded wire is more flexible and resistant to breaking than solid wire.
Stranded wire is commonly used in applications where flexibility is required.

Wire is used to bear mechanical loads, often in the form of wire rope.
Wire can refer to an electrical cable used for electricity and telecommunications signals.
Wire can be made in various cross-sections for decorative or technical purposes.
Edge-wound coil springs, such as the Slinky toy, are made of special flattened wire.
Wire is used in the production of high-efficiency voice coils in loudspeakers.

Wire is commonly formed by drawing the metal through a hole in a die or draw plate.
Wire gauges come in various standard sizes, expressed in terms of a gauge number or cross-sectional area.
Precious stones like diamond or ruby can be used in the draw-plate to maintain the size of the holes.
Wire drawing can be done manually or through modern machinery.
Insulating and jacketing of wires and cables is done by passing them through an extruder.

Winding of motors, transformers, inductors, generators, and speaker coils.
Coaxial cable used as a transmission line for radio frequency signals.
Speaker wire for low-resistance electrical connection between loudspeakers and audio amplifiers.
Resistance wire used for heating elements or wire-wound resistors.
Copper magnet wire used in various applications, such as winding wire.
