Copper. Alloys of copper are used in most of the electrical wiring indoors and/or outdoors.
However, aluminum is used in long-distance high-tension electrical lines because by weight it's a better conductor than copper is (and because it's less expensive and stronger). An aluminum wire needs to be thicker than a copper wire in order to have the same current-carrying capacity. However, even though it's thicker, it weighs less, which means the relatively expensive transmission towers can be spaced further apart without the wire sagging too much.

∙ 8y agoCopper and aluminum, both are good conductor of heat. When a comparison is made between these two copper is better. Therefore, copper wires are preferred over aluminum wires for passing electric current.

∙ 12y agoNo, Copper is nearly twice as conductive as aluminum. Among metals copper's conductivity is second only to that of silver.

Which is best copper or zinc?
copper and zinc both are conductive materials but as copper is in lower position than zinc in electromotive charts zinc is more than copper but other material properties like corrosive force,strength are better for copper. so for daily use copper is better than zinc.
What is more cheaper aluminum or copper?
I wasn't too sure about this but Im sure the answer is aluminium. Check you grammer: What is cheaper or what is more cheap
Why electric wires made up of copper or aluminium?
Probably not. Both gold and aluminum have poorer conductivity than copper. If copper is rated at 100, then aluminum is 57 and gold is 65. Gold is sometimes used to electroplate electronic connectors, not so much because of is conductivity, but because it is so resistant to oxidation. Aluminum is a good choice where weight is a factor, such as in high-voltage transmission lines. Other than in a few special cases, copper is the better material for electrical wiring.
Why is copper more widely used as an electrical conductor than silver?
Silver is more expensive than copper and aluminum and less abundant so it is more economically feasible to use other metals.
Which conducts elctricity more efficiently copper wire or aluminum?
Copper is a better conductor than aluminum. Silver is even better. I think that at room temperature, gold is best, but superconductors at their critical temperatures are best.
Does aluminum or copper produce more electricity?
Copper is more electrically conductive than aluminum (this is because aluminum forms a monomolecular layer of non-conductive aluminum oxide on its surface).
Is silver a better conductor of electricity than copper?
no copper is more conductive YES, silver is more conductive than copper.
Is mercury more electrically conductive than copper?
No. Copper is the second most elkectircally conductive of all metals. Silver is the most conductive.
Is aluminum electrically conductive?
Yes...all metals are will conduct electricity.
Is mica more or less conductive than aluminum?
Less.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
What makes Gold Atoms more conductive than other Atoms?
Gold is more conductive than other atoms (except silver and copper) because of its high concentration of free electrons. Silver and copper are more conductive than gold, but gold has the advantage of being corrosion resistant.
What element is more conductive than copper?
Silver but it's more expensive so we tend to use copper more for conducting electricity
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
What characteristic of copper and aluminum causes the to be good conductors what is the effect?
They are both metals. The effect is that copper is more safer than aluminum. From Leah :)
