Most electrical wires use unalloyed copper. The exception is high-power overhead lines that use aluminium for its low density, which means there is a lot less mass for the towers to support, so they are lighter and less expensive.
Aluminium overhead cables are either ACSR - aluminium core, steel reinforced, which uses multi-strand cables with steel strands in the centre; or AAAC which is all-aluminimum alloy conductor.
AAAC cables use an aluminium-magnesium-silicon alloy with silicon 0.5-0.9%, magnesium 0.6-0.9%, iron 0.5% max, copper 0.1%, manganese 0.03%, chromium 0.03%, zinc 0.1%, boron 0.06%. The purpose of adding other elements is to increase the tensile strength of the conductors so they can be tensioned up without too much dangling.

What metal is used in aircraft construction?
aluminum alloys because aluminum is quite strong for how light it is
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student
What is wire welding?
A form of arc welding in which the electrical energy used to weld the metal is conducted through a wire that is fed from a spool to act as a filler metal.
What raw materials are in toy cars?
If it is a metal or diecast car....The bodies and chassis of the cars were actually made of *ZAMAK (German) "zink, aluminium, magnesium and kupfer", also known as Zamac (US) "zinc, aluminum, magnesium and copper". The New Jersey Zinc Company developed zamak alloys in 1929. Zamak has also been referred to over the years as pot metal or white metal. The most common zamak alloy is "zamak 3", but "zamak 2", ""zamak 5 and "zamak 7" are still commercially used. These alloys are most commonly used for die cast. Zamak alloys (particularly #3 and #5) are frequently used in the spin casting industry.Some toy cars have also been made of tin and plastic.
Why is copper used to make wires?
Copper has very high electrical conductivity, low resistance, good tensile strength and ductility, and is normally not brittle. Other materials with higher conductivity are either too expensive (like gold) or too brittle to be good candidates for wire.
Which metal is commonly used in electrical wires?
Copper is the most common metal used in electrical wires due to its high conductivity and ability to easily carry electrical currents.
What is metal usually used for?
Copper is frequently used for electrical wires. Aluminium is cheaper but breakable.
What is the periodeic table of elements metal used in wires?
Copper is the metal commonly used in wires due to its excellent electrical conductivity and corrosion resistance. It is a key component in various electrical wiring applications due to its ability to efficiently conduct electricity.
What metal conducts electricity well and is used for wires and pipes?
Copper is the main metal used for this purpose.
What is a metal that is often used in wires that conduct electricity?
Copper, and to a lesser extent gold, are used in conductors.
What is the most ductile metal which is not used to make electrical wires?
Lead could fall into that category.
Why electrical wires are not made of graphite?
Ignition wires for engines in cars and other vehicles are often made from carbon because of its excellent performance in hot conditions but, for most other general electrical wiring purposes, copper is commonly used.Silver and gold are better conductors of electricity than carbon or copper but they are much more expensive metals so they are only used for specialized applications. For example very thin wires made of gold alloys are used for integrated circuits and silver alloys are used for some switch contacts.
What metal alloys are used for human branding?
alloys are a base metal with a little of a similar metal mixed into it to make them harder for everyday use and are used for structual purposes such as building
Why is silver not used for electrical wires if it is such a good conductor of electricity?
Silver is not used for electrical wires mainly for two reasons. Silver is too expensive to use and it is a soft metal which is not suitable for electrical wires.
What mineral is used to make electrical wires brass coins plumbing and jewelry?
Not a mineral but a metal- copper.
Why can't a metal that is used as electrical wires be in liquid form?
It can is is (check out Mercury switches), but it gets complicated and expensive.
Why are many metals used as alloys?
alloys are probably cheaper to make and stonger then an element or a simple metal. Alloys are easier to make. It is difficult to find a simple metal.
