Copper wires are made of copper and aluminimum wires are made of aluminimum.
Don't work aluminimum wiring unless you know exactly what you are doing. It will react with copper wire and wiring devices and will start a fire. There is special grease and wiring devices to prevent this that you need to use. If you have aluminimum wire, make sure you do your homework.
-------
The electrical capacity of any type of cables/wires are depending on the heat withstand capacity of the material wich can be calculated with the product of square of current, Resistance of the material and Total time for flow of current. I2RT. Resistance again can be calculated as R=rho*L/A where rho is the resistivity, L is the length and A is the area of cross section. So for a fixed current flow and fixed Length of wire the area of cross section of the cable is directly propotional to the resistivity. resistivity of copper is 1.68x10 power -8 and that of Pure Aluminum is 2.82x10 power -8. So.. for a specific current flow, an aluminum cable size shall be 1.7 times that of copper cable. This also is not recommented as the Aluminum resistivity varries with the alloys and even with casting. 2.5 times the size of copper can be recommented for Aluminum cables. Also as the temporature expansion of Aluminum is 3 times that of copper. So all the termination and joining areas shall be treated more sensible that of copper.
No need to be afraid to use Aluminum cable if you work with the proper recommented size.

∙ 9y agoCopper instead of silver wiring is used for electrical wiring because copper is a good conductor of electricity. Likewise, silver is more expensive to use for wiring than copper.

Will a magnet pick up more nails when covered in copper wire or metal wire?
copper wire because we all know that metal strengthens the magnetic field but copper has a special property that strengthens the magnetic field further so copper is the answer P.S. i already did the experiment
What is the difference between copper and silver?
Silver conducts better then wire, however it costs more so it's not commonly used.
How do you tell the difference between copper and aluminium wires?
Shut the main breaker off on your distribution panel. Remove the cover. Look at the colour of the wires that are connected to the breakers. If they are silver in colour then they are aluminum wires. If they are copper in colour then they are copper wires. Replace the panel cover and turn the main breaker back on.
What is tinned copper wire?
copper wire that is coated with tin
Is copper wire heterogeneous?
A copper wire is considered to be a homogeneous system.
Performance difference between aluminum-based magnet wire and copper-based magnet wire?
According to different conductors, magnet wires can be divided into copper-based magnet
The difference between enameled wire and magnet wire?
An important type of winding wire
If you circulated copper wire to magnet and pass current through copper wire it then power of magnet is incrase?
The copper, technically, wouldn't increase it's power but rather extend the magnetic field of the magnet.
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
What is the difference between copper bare and copper millberry wire?
Mexicans are very interesting.
What will be attracted to ( or repelled by) a magnet?
a copper wire carrying current and another magnet.
Will a copper wire not carrying a current be attracted to a magnet?
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
Which of the following will be attracted to or repelled by a magnet?
A copper wire carrying current, Another magnet, An iron horseshoeA copper wire carrying currentAnother magnetAn iron horseshoe
Can copper wire be made into a magnet?
The copper wire has to be wound around a iron core to get the full effect of electromagnetism.
What does copper wire and magnets have to do with Electricity?
a magnet moved through a copper coil makes electricity
Can a magnet be used to produce electricity?
A spinning magnet inside a coil of copper wire will produce electricity.
Can magnets attract a copper wire?
No, copper is not magnetic. That said, if the copper wire has an electric current flowing through it then it will generate its own magnetic field around the wire. It seems feasible that this could be enough to move the wire if you have another magnet near it.
