It's partly a convention of terminology; similar items are made from plastic or fabric and they are called "string" or "strands".
You may be asking why metals are used for electrical wiring; that's because metals are conductors - that's almost a definition of what a metal is - metallic elements have surplus electrons and conduct electricity.
Their high conductivity is why transition metals are used to make electrical wires.
Electrical wires are usually made from metals.
Because of thier high conductivity
The ability to pull metals into wires is called ductility. Metals are ductile, non-metals are not. Ductility is a physical property.
The physical and chemical properties of metal can differ between the elements but if we try and generalize. Physical properties are that they are hard, dense, shiny, malleable (can be bent), ductile (can be pulled into wires), a good conductor of heat and have high melting points meaning that they are solid at room temperature Their chemical properties include being good electrical conductors, they make metallic bonds (ionic bonds with non-metals) and their atoms are arranged in a lattice. They release hydrogen when reacted with acids and are usually cations (positive ions).

The two most comon metals that electrical wires are made from are aluminum and copper.

Out of all the common metals copper is the best electrical conductor. Only silver is slightly better.
No, metals are good conductors of electricity due to the presence of free-flowing electrons in their atomic structure. These electrons are able to carry electrical charge through the metal efficiently.
The purpose of a wire is to carry some sort of electrical signal. This requires that the electrons in the material be able to move freely. Materials with free movable electrons are called "metals".
Because metal is one of the greatest conductors of electricity.
Electrical conductors are used in wiring. They allow electricity to flow through the wire and into the item needing the electrical power. Wires are usually made of copper or aluminum because these metals are good electrical conductors.
