Mainly copper.
Both copper and aluminum wire is used in the electrical trade. Copper in the smaller size wires but aluminum becomes more viable when bigger size wire is needed. This is usually 200 amp services and larger. When aluminum wire is used for a specific amperage, one size larger is required than when using copper. The money savings on aluminum wire over copper wire in the larger sizes is about 20%.
Electrical wires are typically 'drawn' through a series of pulling machines and dies from an extruded copper source ingot or billet
The copper (in most wires) starts as a large 'blank' or roughly unformed mass of copper. The copper is then usually extruded under extreme heat and pressure to form a thicker and longer strand. This strand is too large to be used as wire, but starts the process.
The strand then is pulled through a series of subsequently smaller dies & pullers, with each set of pullers and dies making the diameter of the wire smaller, and also increasing the length of the wire.
After the copper is at the desired diameter, is it then passed through a continuous coating process of an insulting material (Vinyl, PVC, ABS, Shellac, Varnish... etc)
After the insulation, some wires will have manufacture and trade information printed on it in another continuous process...
Any metal. Copper is preferred for its high conductivity whereas Aluminum is used in high tension lines because of its light weight. (And sometimes steel for its strength.)
No. Just copper, and possibly an enamel or plastic insulating jacket.
The most used metal to make electric wire is copper (Cu).
Most electrical wiring is made of copper.

Metal that can be pulled into a wire is ductile. The most ductile metal is gold.Copper (or alloys containing great amounts of copper) and aluminum (alloys) are the most common electric conductors with silver, gold and other rare metals used for specific purposes.Various iron alloys are made into cable wire that are to withstand high tensile loads.
Approximately 127 cm length of a wire with a diameter of 1mm can be used to make a 1cm cube of metal.
Yes, because to conduct electricity you need a metal wire, (usually copper). However they have a plastic outer coating (sheath) which protects them and insulates them.
Electromagnets.
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.

Electric fuse wire is not made of a single metal but an alloy made of tin (63 %) & lead (37 %). The cross sectional area determines the melting point at a certain current (amps) and is also rated as volts / rating.
To answer the first part of your question the bulb looks sort of like an egg but has a more rounded top made of either clear or colored glass and the bottom consists of a metal piece that has the wire inside it. The wire is a thin piece of metal made of copper and an electric current runs through this wire creating light.
You melt the metal and pour it into a thin mold the size of the wire you want.
