Aluminum Wire used in aerospace, marine, construction, and automobile industries. It is a heat treatable wrought alloy with intermediate strength.
Aluminum is such a good conductor of electricity that even aluminum foil can be used as a conductor. Foil tends to be too delicate for most industrial applications, but it just goes to show the advantages of this material.
One of the most familiar and oldest applications for aluminum is electrical wire. Most of the insulated power cables in America’s electrical supply are made of aluminum, for the aforementioned weight and cost reasons. Copper cables would weigh much more than the aluminum ones, that’s why aluminum has been found in the nation’s power grid as far back as the late 1800’s.
Besides overhead power cables, aluminum wiring can also be found in some airplanes, homes, electronic devices and appliances such as fans, lamps and more.
With that in mind, in smaller wire sizes, copper will often be preferred to aluminum. This is because aluminum wiring does have one drawback that you should be aware of: it can be extremely corrosive when combined with other metals, meaning that you can’t use aluminum wire with copper conductors, as an example. Because copper was used in many of the first electrical devices, much of our infrastructure relies on copper. Switching over to aluminum would be prohibitively expensive, and that’s the reason why aluminum wiring was largely relegated to overhead power cables for many decades.
