Instead of what? Aluminium is used in electricity transmission cables because the slight sacrifice in conductivity is more than made up in its ability to support itself; you can always add more of something to lower resistance, but if it is too weak, it is too weak.
Copper is used in the wiring for just about everything else, from home circuits to vehicle electricals.

What advantages of using scrap iron to extract copper from a copper salt?
Using scrap iron to extract copper from a copper salt solution is cost-effective because iron is cheaper and more readily available than other reductants. Additionally, scrap iron helps in the reduction of copper ions to copper metal due to its high reactivity, making the extraction process efficient.
Is oxygen more reactive than copper?
Yes, oxygen is more reactive than copper. Oxygen can readily react with many materials, including metals like copper, to form oxides. This is why copper often forms a tarnished or oxidized surface when exposed to air.
Is copper surface hydrophobic?
No, copper surfaces are typically hydrophilic, meaning they have an affinity for water and will readily allow water to spread across the surface rather than bead up.
How copper can be extracted by hydrometallurgy but not zinc?
zinc is more electropositive and therefore is highly reactive metal.hence it can not be easily displaced from its solution of ZnSO4.on the other hand,copper is less electropositive and can be readily displaced from its solution more active metal such as zinc. Zn + Cu2+ ------> Zn2+ + Cu
Is sugar more soluble than copper sulphate?
Yes, sugar is more soluble than copper sulfate in water. Sugar dissolves readily in water due to its molecular structure, while copper sulfate requires more energy and agitation to dissolve completely.
Why are copper wires used instead of steel wires?
I think copper is cheaper.
Why is copper-nickel alloy used for 'silver' coins instead of silver?
There are a number of reasons:Copper-nickel alloy is much cheaper than silverIt is harder, so lasts longerIt tarnishes less readily than silver
Why is copper us as electric cable instead of silver?
Copper is much cheaper but still does the same job almost as well as silver.
is brass or copper cheaper?
Copper is cheaper than brass.
Why is it easier to make musical instruments from brass instead of copper?
Actually, copper is softer than brass, and easier to work. The reason musical instruments are made from brass instead of pure copper is because that alloy with zinc is much more durable than copper alone, and does not as readily corrode.
What advantages of using scrap iron to extract copper from a copper salt?
Using scrap iron to extract copper from a copper salt solution is cost-effective because iron is cheaper and more readily available than other reductants. Additionally, scrap iron helps in the reduction of copper ions to copper metal due to its high reactivity, making the extraction process efficient.
Is it cheaper to recycle copper than to use new copper?
It can be up to 90% cheaper to recycle copper
Is copper cheaper than stainless steel?
Yes, brass is cheaper than copper.
If silver is a better conductor than copper then why is copper wire used in daily life instead of silver wire?
The price of copper today is $3.43 a pound. The price of silver today is $12.90 an ounce. Copper is much cheaper.
Why is copper good for plumbing?
Copper is NOT good for plumbing. It was once, when there was no alternative. Now many superior products like PEX are available. They are cheaper, more lasting and more efficient to fit than copper.
Why are copper wires preferably used in electrical installation?
copper next good conductor to silver . it is cheaper .malleable ductile mechanically strong abundantly available so we use
Why is copper usually used to make electrical wires instead of iron?
it is cheaper,conduct electricity better then iron,more ductile and maleable
