You can after all make effective house wire out of steel, however it has a higher resistence than copper so it wastes more energy to use it. Sadly the better a metal conducts electricity the more it costs, for the most part at least. Copper is better than iron, silver better than copper, gold better than silver, platinum better than gold and so on.
False.
As falconoffury have written, silver is the best conductor of electricity.
Very good one but still inferior to copper is aluminum.
It is still expensive enough to steal in any case.
Gold is used in electronics due to a very high plasticity (easy to make tiny wires etc) and corrosion resistance, far better then silver has.
Electric conductivity is marginally poorer though.
On the other hand price of mineral roughly grows with heat conductivity.
So for example diamond is the most expensive mineral as well as being best
solid conductor of heat known.
Cheaper ruby or emerald are also a very good heat conductors, for example better than copper is.
Yeah, after he corrected me TWO YEARS AGO I looked it up and was surprised at how faulty my memory had been. Since then I try and look up 'common knowledge' facts before reoeating them.
