Copper is more thermally conductive than aluminium but again, when the larger conductor sizes are factored in the differences are reduced. The better the thermal conductivity the better the short circuit performance of the conductor.
Copper has a conductivity of about 6·10 7 S/m, while rubber has a conductivity of about 10 -14 S/m, a difference of 21 orders of magnitude, so to have the same resistance, a rubber wire would have to have 6000000000000000000000 times the cross-sectional area of the copper one.
Why Is Copper a Good Conductor of Electricity? Copper is a good conductor of electricity because the valence electrons are free and repel each other so strongly that it causes the repulsion of other electrons. This essentially forces the electricity down the piece of copper, or conducts it down the metal.
I read somewhere that very thick wires are generally better conductors than very thin ones. Is this true? If yes, then would a very thick rubber wire be a better conductor than a very thin copper wire? Edit: By rubber wire, I mean a wire made entirely of rubber, not a copper wire insulated with rubber. This is purely a theoretical question.

To get an electrical current to flow through metals, the power source has to fight against resistivity. The lower the level of resistivity, the more electrical conductivity a metal has. And since copper wire has a low level of resistivity, it’s a fantastic electrical conductor.
Is copper the best conductor?
Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed. Copper’s core electrical function is related to the transmission of electricity and power generation.
Is metal or rubber a better conductor?

What is the main difference between aluminum and copper?
Copper not only has a higher conductivity than aluminum, but is more ductile, with relatively high tensile strength, and can be soldered. Aluminum has less conductivity, about 60 percent of copper, but its lightness enables it to make long spans possible. Summary: 1.
Is aluminum and copper wire the same size?
The National Electric Code (NEC) provides specifications for aluminum wiring (AA-8000 series electrical grade aluminum alloy) and the minimum conductor size. Usually, aluminum wiring is larger when compared to copper wiring size. A copper wire may be listed as 14 AWG, while the aluminum would be 12 AWG.
When sizing from copper to aluminum The aluminum wire should be?
A commonly used rule-of-thumb for converting the two conductor metals is to have aluminum two AWG sizes larger than copper for equivalency.
