Wire is generally made by pulling a rod through progressively smaller dies until it reaches the correct diameter. This work hardens the alloy and can make it too hard and stiff to use. Most wire is annealed after drawing to soften it and make it more usable. Annealing is done at a temperature of around 70 - 80% of the melting temperature on a scale that starts at absolute zero (-273.15 degrees Celsius or 0 Kelvin). Annealing allows the atoms to rearrange themselves into a lower energy state. For a work hardened material the dislocations can sort themselves out and even disappear as new, much more perfect crystals arise. Copper work hardens so much that it is normally annealed one or more times between drawing steps. For electrical wire it is generally drawn to final size after the last annealing - this gives a smooth, shiny surface and a wire that has some stiffness, but not too much.

No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
Copper
The copper wire has to be wound around a iron core to get the full effect of electromagnetism.
copper and tin
copper wire
castings made from copper alloy are a higher grade of copper than the copper in wire. Also, the insulation on the copper wire needs to be removed,
Yes, it is possible.
Copper wire
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
Copper is a very good conductor of electricity, and is easy to shape.
copper is an element. but copper wire is a processed element.
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
