Possibly old wiring corroding. Could be caused by loose connections. May have to run new wires. Consult a licensed electrician.
Corrosion involve chemical reactions - and these are chemical changes.

Copper is not thermosetting - if you heat it up enough it will melt - nor is it plastic.
A copper penny builds up a layer of corrosion on its outsides. Probably copper oxide. The cleaning just dissolves the outer corrosion and leaves a new outer layer of copper. CuO + HNO3 --> Cu(NO3)2 + H2O ... the copper nitrate is dissolved in the acid solution and leaves 'clean' copper behind.
Any metal that is higher than iron in the electrochemical series coupled to it will speed up the corrosion. As an example, a copper pipe in contact with steel will accelerate the corrosion of the steel.

it is coated in copper. copper prevent corrosion.
Copper turns green after a while because of weathering and corrosion. It is in general the Oxygen in our atmosphere that bonds with the copper, forming a protective layer of "green" oxydation or corrosion. Further information: Many buildings have copper-roofs. It is a metal that is easy to cut and form. It is also highly corrosion resistant because the corrosion formed also protects it from further corrosion. Acid rain however is able to wash away part of the corrosion formed. This mean that in highly polluted areas, Copper is not such a good choice. The Statue of Liberty used to be the iconic copper color.

Corrosion of the copper
If the water's pH is more acidic (lower pH) then the effects of copper corrosion will be faster and more pronounce. If the water is less acidic (Higher pH) copper corrosion will take longer and be less pronounce.
If copper is present, the solution will turnblue...
Copper can be stored in bottles containing water, such that none of the copper is exposed to air, as this can cause the corrosion of copper.
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.

The corrosion resistance of copper is great! But if the hardness was better and the strength it would be way better than titanium in some cases (not the melting point)!!!
