Copper wire can turn black due to a process call oxidization. When the copper comes into contact with oxygen, the reactions slowly cause the wire to form a black and sometimes green coating. Copper wires will turn black when in contact with moisture.
What causes green corrosion on copper wire?
Copper turns green because of chemical reactions with the elements. Just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer layer, copper that is exposed to the elements undergoes a series of chemical reactions that give the shiny metal a pale green outer layer called a patina.

What kind of wire will not rust?
Copper, brass, and bronze do not rust for the same reason as aluminum. All three have a negligible amount of iron in them. Therefore no iron oxide, or rust, can form. However, copper can form a blue-green patina on its surface when exposed to oxygen over time.
Does copper wire tarnish easily?
The copper is also the reason sterling silver tends to tarnish – over time, copper reacts with oxygen and releases oxidation on the surface of the material, which is also known as patina.
