Every metal (except Gold) is corrosive. The metal chosen for use as electrical wire is based on cost and conductivity.
If Gold is rusted/oxidized and left to sit for eternity it will typically revert back into pure Gold, which is why it is used in situations where corrosion is a problem that warrants the extra cost.
Prices circa 2012:
Copper 16.78 nΩ·m at ~$3.50/lb
Aluminum 28.2 nΩ·m at ~$0.90/lb
Gold 22.14 nΩ·m at ~$256000.00/lb

What common metals are used for electrical wiring?
Copper and aluminum (or copper clad with aluminum) are often used in wiring. New aluminum connection is now limited to use service-connections by some electrical codes and can no longer be installed for branch circuit wiring.
Is aluminum an example of an electrical insulator?
No, aluminum is a good conductor of electricity due to its ability to carry electric current. It is commonly used in electrical wiring and other electrical applications.
A silver-gray metal used in electrical wiring and the structure of planes automobiles and other?
aluminum
What element is used to make electrical wiring because it is less dense than copper?
Aluminum.
Why is the best conductor not used for household wiring?
Copper is an excellent conductor of electricity, but it is more expensive than aluminum. Aluminum is commonly used for household wiring as it is cheaper, lighter, and still has good conductivity. Additionally, aluminum wiring is safe when installed properly and can meet electrical codes and standards.
What are 3 conductors used in your home?
Copper, aluminum, and silver are commonly used conductors in homes for electrical wiring and circuits.
What materials is electrical wiring usually made from?
Electrical wiring is commonly made from copper or aluminum. Copper is preferred for its high conductivity and corrosion resistance, while aluminum is used for its lighter weight and cost-effectiveness. Both materials are suitable for carrying electrical currents safely and efficiently.
Is aluminum wire safe to use for electrical wiring in homes?
Aluminum wire can be safe for electrical wiring in homes if installed properly and used with appropriate connectors. However, it is important to follow specific guidelines to prevent potential hazards such as overheating and fire risks.
Will you find aluminum used for conducting wire?
Yes, aluminum is commonly used as a conductor in electrical wiring due to its good conductivity and relative cost-effectiveness compared to copper.
Why is brass not used for electrical wiring?
Brass has high electrical resistance compared to other metals like copper and aluminum, making it less efficient for conducting electricity. Copper and aluminum are preferred for electrical wiring due to their excellent conductivity and cost-effectiveness.
Does aluminum have conductivity?
Yes,Aluminum have conductivity because it is a metal
How much electrical wiring is copper?
Most electrical wiring is made of copper due to its high conductivity and flexibility. Copper is preferred for electrical wiring as it can efficiently carry electricity while being durable and resistant to corrosion. However, there are also some electrical wiring products made from aluminum, which is a less expensive alternative with slightly different properties.
