One of the significant attributes of many metals is the capability to conduct electricity, and aluminum is just one of the best performers in this application. Together an electrical conductor, few materials deserve to rival aluminum. That’s why so many industries and also technologies, indigenous high tech consumer devices come aerospace come heavy-duty transformers, have actually turned to aluminum alloys together a solution.

You are watching: Why does aluminum foil conduct electricity

The chemistry composition the metal method that in many cases, the metallic bonding permits for the conduction that electricity. Metallic atoms are surrounded by constantly relocating electrons that allow electricity to easily move among the ions. If aluminum is no the finest metal conductor, it is just surpassed by pure silver (#1), pure copper (#2), and pure yellow (#3). In ~ the other end of the spectrum, stole is a middling conductor, when stainless steel is among the worst.

Because the the noticeable expense that would be involved, silver and gold space not viable alternatives on an commercial scale. That leaves only copper as a more feasible conductor the electricity, and when you to compare the two, aluminum has actually many benefits that do it an ext appealing to manufacturers and designers.

Today fine be examining the means aluminum alloys are provided in electric devices and what you need to know when picking a grade that is ideal for you.

Aluminum is normally a conductor

First, aluminum on its own is just one of the best metals because that conducting electricity. Aluminum is actually qualified of what is known as supervisor conductivity, i beg your pardon is when the electric resistance the a product vanishes and also the magnetic flux areas are expelled. In a typical metallic conductor, the resistance will progressively decrease as it cools, when in a superconductor over there is a an essential temperature in ~ which the resistance will all of sudden drop come zero. This method that an plain electric current can persist indefinitely v a loop of superconducting wire without the require of a power source.

In aluminum, the superconducting critical temperature is 1.2 kelvin. Its critical magnetic ar is around 100 gauss. An additional attribute of aluminum is the it’s paramagnetic, so it does not must worry around static magnetic fields. It must be detailed however the it deserve to be strongly affected by a an altering magnetic ar as the an outcome of the induction that eddy currents.

When contrasted to copper, aluminum exhibits just over fifty percent (61 percent to it is in exact) the conductivity the copper. Top top its face, this appears to imply copper is the far better option together a conductor, but that neglects the truth that aluminum is one-third the weight of copper. Therefore, if you have two metal wires, one copper, one aluminum, qualified of conducting the very same amount that electricity, the aluminum one will weigh half as much. Aluminum additionally tends come be much less expensive because that this reason.

What applications most frequently rely top top aluminum together a conductor?

Aluminum is such a good conductor of electricity that also aluminum foil have the right to be provided as a conductor. Foil has tendency to it is in too fragile for most commercial applications, however it just goes to display the advantages of this material.

One of the many familiar and oldest applications because that aluminum is electric wire. Most of the insulated strength cables in America’s electric supply are made the aluminum, for the aforementioned weight and also cost reasons. Copper cables would weigh much much more than the aluminum ones, that’s why aluminum has been uncovered in the nation’s power grid together far ago as the so late 1800’s.

Besides overhead strength cables, aluminum wiring can additionally be found in some airplanes, homes, electronic devices and appliances such together fans, lamps and also more.

With that in mind, in smaller sized wire sizes, copper will frequently be preferred to aluminum. This is because aluminum wiring does have actually one drawback that you need to be mindful of: it deserve to be extremely corrosive when an unified with other metals, definition that friend can’t usage aluminum wire with copper conductors, together an example. Because copper was supplied in plenty of of the very first electrical devices, lot of our framework relies on copper. Switching over to aluminum would certainly be prohibitively expensive, and that’s the reason why aluminum wiring was mostly relegated come overhead strength cables for plenty of decades.

More recently, however, more and an ext copper wiring is being changed by aluminum. This method that it’s crucial for girlfriend to do your research and also understand just how your application will be used and also what the existing wiring needs (copper or aluminum) are.

What room aluminum electrical cables make of?

There are 4 main varieties of aluminum power cables. The very first is well-known as all Aluminum Conductor (AAC) and also consists of electric Conductor grade aluminum. This aluminum alloy is not an extremely strong, and also although its conductivity is 61% the of copper, it is not seen very often in transmission lines. Friend will discover it in urban circulation lines, which tend to have shorter spans and higher requirements because that conductivity.

Next is every Aluminum Alloy Conductor (AAAC), i beg your pardon is make from alloy 6201. This alloy offers great strength, with about 52% the conductivity that copper. It is frequently used because that distribution and is especially helpful in coastal areas due to the fact that of that is corrosion resistance.

Aluminum Conductor, stole Reinforced (ACSR) combine a steel core v layers the aluminum 1350 alloy wires wrapped around it in spiral. Through the substantially increased strength provided by the steel core, there is much much less sag, do this kind of cable suitable for both transmission and also distribution. You will certainly often discover it offered in flow crossings and also other areas where greater strength is necessary.

Finally, Aluminum Conductor, Alloy Reinforced (ACAR) combine aluminum 1350 wrapped roughly a 6201 aluminum alloy core. This results in boosted electrical and also mechanical properties than ACSR, make it more reliable, though much more expensive than other cables. It have the right to be found in both overhead transmission and distribution lines.
