Copper combines several properties that have traditionally made it preferred for most electrical wiring. Copper is a good electrical conductor, provides a good contact surface, is ductile (is easily bent repeatedly without breaking) and it is not too expensive.
Aluminum is cheaper, lighter, softer, and therefore easier to bend than copper but is less desirable because it expands and contracts more than copper and produces loose connections. Many houses were built in the US in the 1970s with aluminum but most of them burned down. Aluminum is no longer allowed in houses in the US except for service entrance conductors. In commercial and industrial installations aluminum is still allowed but connections are required to be re-torqued once a year. That is quite a labor-intensive project. -- Sparkfighter
What else can I help you with?
Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
What metal conducts electricity well and is used for wires and pipes?
Copper is the main metal used for this purpose.
Why copper wires are used in householding wires?
It's because copper is the best conductor of electricity, other than silver which is slightly better but too expensive.
Does copper wire produce electricity?
Copper wire itself does not produce electricity. However, when copper wire is part of an electrical circuit and connected to a power source such as a battery or generator, it can transfer electricity by allowing the flow of electrons through it.
Why are transition metals used to make electrical wires?
Transition metals like copper and silver are used to make electrical wires because they have high electrical conductivity, meaning they allow electricity to flow easily. They are also ductile and can be easily drawn into thin wires without breaking, making them ideal for conducting electricity over long distances.
Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
What element is used for wires that carry electricity?
Copper
Why is copper used for telephone wires?
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
In what proportion copper is used to make electric wires?
Usually, you use ETP (electrical grade) copper, which is at least 99.9% pure. It could be different for special applications.
What is a metal that is often used in wires that conduct electricity?
Copper, and to a lesser extent gold, are used in conductors.
Metal that is often used in wires that conduct electricity?

Metal often used in wires that conduct electricity?
Copper is the most common.
What metal conducts electricity well and is used for wires and pipes?
Copper is the main metal used for this purpose.
What is used to make wires and pipes?
copper
Why is steel not used for electric wires?
Because steel is not a good conductor of electricity. Copper is the best conductor for electricity.
Why copper wires are used in householding wires?
It's because copper is the best conductor of electricity, other than silver which is slightly better but too expensive.
Why is copper commonly use to make electric wires?
Copper is commonly used to make electric wires because it is an excellent conductor of electricity, allowing for the efficient transfer of electricity through the wires. Copper is also highly conductive and ductile, making it easy to shape into wires for various electrical applications. Additionally, copper has good corrosion resistance, ensuring the longevity and durability of the wires.
