- High electrical conductivity: Aluminum has very high electrical conductivity. So it is good for making electrical cables.
- High ductility: Its ductility is very high which makes it perfect for drawing large aluminum cables.
- Light weight: Aluminum weighs about one third of copper, nickel, brass, and steel. Its specific gravity is 2.7. So the aluminum cables are very light weight, hence suitable for long distance cabling. They are also useful in overhead cabling.
- High resistance to corrosion: Aluminum is resistant to corrosion which makes it a good choice for manufacturing underwater cables.
- High strength: The high strength of aluminum prevent it from creeping even under high load. However, on overhead transmission lines it is sometimes strengthened with steel.
- Economical: Aluminum is one of the most economical elements and hence the aluminum cables are cheaper than copper, their nearest competitor.
- Physical properties: Aluminum is silvery white metal and highly reflective to heat and light. It is easily machinable and can have various surface finishes. It is easily recyclable.
- Non magnetic: Aluminum is non-magnetic in nature which is an important property for making armors and raceways.

∙ 16y agoBecause it is great at conducting a current and copper is expensive (so are the other alternatives like silver and gold) The first computers used it until the components got too small for the aluminium(it over heated).

∙ 15y agoAluminum conductors cabled around a steel support wire are commonly used for large high voltage transmission lines because aluminum is much less expensive than copper. The steel support wire is needed because aluminum has relatively low tensile strength. Low voltage household, office, and factory electric wires are usually copper, which does not have the corrosion problems common to aluminum wires.

∙ 13y agoIt is great conductor and it is lighter and cheaper but can not handle heavy amperage, if you wanted to run same load through aluminum as copper the aluminum wire would need to be thicker than the copper.

∙ 14y agoCopper and aluminum metals are used for making wires because:
- they are ductile, that is, they can be drawn into wires.
- they are good conductors of electricity.

∙ 12y agoElectrical transmission wires are made from aluminum and steel. The cable in the electrical trade is known as ACSR. The letters stand for aluminum conductor steel reinforced. To keep transmission costs down, long spans of cable are used between towers. To use copper in such spans would require more towers to support the heavier wire conductors. The straight use of aluminium would not work either because of the softness of aluminum and if flexed sufficiently would break. A steel messenger wire with the aluminum conductors wrapped around it fit the bill for a light weight and strong cable. Due to the steel messenger wire installed in this type of cable, it is able to span great distances between towers and high voltages can be applied to it because of the wire spacings and distance between other cables on the same tower.

Is the aluminum used to make a soda can a compound?
No. Aluminum is an element
Why does security alarm systems use cables with one conductor Aluminum and one Copper?
Both conductors are copper. One is just electroplated so it looks silver. This is so you can know which conductor is which when you hook them up. The copper-colored conductor is traditionally used as the positive, or plus wire. The silver-colored wire is used for the negative or minus wire. Some cables use a foil shield. The shield is mylar (polyester) coated with aluminum. The shield is not really one of the conductors, it is only used to drain away interfering signals before they reach the inner conductors, so it need not be a super good conductor. Aluminum is used for the foil shield partly because it is lightweight, but mostly because it's much cheaper than copper.
What is the molecular size of aluminum stearate?
Aluminum stearate has a molecular weight of 876.0 Aluminum stearate is used in cosmetics, often as an emulsifier. The aluminum stearate comes from stearic acid.
What is a chemistry name for AL2O3?
Aluminum Trioxide, it is an ionic compound. Aluminum Oxide. It is an ionic compound, therefore no prefixes are used in naming.
Why is gold so expensive and aluminum is so cheap?
Gold is much more dearer these days because there is less of it then aluminum. Also aluminum is a renewable source that can be used infinite amount of times. Aluminium is used more in daily life and gold is used for flourishing fashion accessories.But if we actually counted the amount of times aluminum is used then it would be most expensive.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
Why is a mixture of iron and aluminium used in power cables?
Iron strengthens the aluminum
Why is aluminum used for cables instead of copper?
Al is lighter than Cu.
Where and why do you commonly use aluminum in buildings?
Aluminum is commonly used for flashing and for siding. Aluminum wiring for house wiring has fallen out of favor because of fire hazards resulting from improper installation and maintenance but it is still used for entrance cables. Aluminum can also be found in ducts, vents and window frames. Aluminum is used because it is corrosion resistant and relatively inexpensive.
Why copper and aluminum are used in electrical cables?
Because they have low electrical resistance, good enough mechanical properties and aren't too expensive.
Why would a Chevy Corvette be hard to start?
A lot of the time Chevy used aluminum battery cables in their cars,(in particular my 1980) I was continually having starting and battery problems until I replaced the cables with copper.
What is the purpose of Aluminum foil in telephone cable?
it conducts the electricity in the cables
Booster cables - what is the difference in use between copper cald aluminum and 100 copper wire?
It depends on some factors which are not mentioned in the question. The main difference between 100% copper wire and copper clad aluminum is that IF they are the same diameter, then the copper will carry and stand up to more electrical current than the aluminum. If the diameter of the aluminum cables have been upgraded in size, to match the current carrying capacity of the normal copper cables, then the only remaining difference is that copper withstands much more bending and coiling beforethe metal begins to "work harden," and some of the individual wire strands begin to break. In other words, the copper stands up to use better than aluminum. When buying booster cables, read the lables, and make sure that the maximum number of Amps, for which the aluminum cables are capable of carrying, is equal to or greater than the highest rated copper cables. Therefore, IF the copper clad aluminum cables are rated for the same current carrying capacity as copper cables, then there is NO difference in use between the two types.
What are usb cables made of?
They contain PVC,Gold,Copper and aluminum in their various parts.
What are VGA cables primarily used for?
VGA cables are cables which are used with computer electronics. The cables are primarily used to connect the monitor to the computer. Some of these cables are made for specific monitors or devices.
What two metals are commonly used in their purest form?
Copper (electrical wiring and hot water pipes) and aluminum (high voltage cables and soda drink cans).
Why aluminum are use to produce electrical cables?
Aluminum is a metal that is a good conductor of electricity. It has an excellent ratio of conductivity/weight. Also has an excellent ratio of conductivity/price.
