TLDR: Wire is a flexible strand of metal that is used for various purposes, such as carrying electricity, making jewelry, and constructing fences.

Wire is a versatile material that is commonly made by drawing metal through a hole in a die or draw plate. It comes in different sizes, which are expressed in terms of gauge number or cross-sectional area. Wires are used to bear mechanical loads, like in wire ropes, and they are also used in electrical and telecommunications signals, where they can be found in electrical cables.

Wires are usually cylindrical in shape, but they can also be made in different cross-sections for decorative or technical purposes. For example, flattened wire is used in coil springs and special wire shapes are used in voice coils for loudspeakers. Wire has been used for various purposes throughout history, including in ancient jewelry and as a material for making musical instruments.

The production of wire involves drawing the metal through progressively smaller dies or holes in draw plates. This process can be repeated multiple times to achieve the desired diameter and properties of the wire. Electrical wires are often covered with insulating materials, such as plastic or rubber, to protect against electrical shocks. Coaxial cables, which are used for transmitting radio frequency signals, consist of an inner conductor, an insulating layer, and an outer conductive layer.

There are different types of wire, including solid wire, which consists of a single piece of metal, and stranded wire, which is composed of multiple small wires bundled together. Stranded wire is more flexible than solid wire and is used in applications where resistance to metal fatigue is required. Braided wire consists of small strands of wire braided together and is often used as an electromagnetic shield in noise-reduction cables.

Wire has many uses in various industries. It is used in the manufacturing of wire netting, springs, wire cloth, and wire rope. It is also used in electrical and power transmission applications, as well as in the construction of suspension bridges and cages. Wire is used in the production of stringed musical instruments, scientific instruments, and engineered springs. It is also used in the production of magnet wire, coaxial cables, speaker wire, and resistance wire.

In summary, wire is a flexible strand of metal that is used for a wide range of purposes, including carrying electricity, making jewelry, and constructing various structures. It comes in different sizes and shapes, and it can be solid, stranded, or braided. Wire has been used throughout history and continues to be an essential material in many industries.
