Plating may lengthen wire life and makes soldering easier. [13] The cross sectional area of an aluminium conductor must be 56% larger than copper for the same current carrying capability. Electrical conductivity or specific conductivity is the measure of a material's ability to conduct electric current. Conductivity is the reciprocal (inverse) of electrical resistivity.

The first alloy produced was copper melted with tin to form bronze – a discovery so important that periods in history are called The Bronze Age. [3], During the 2000s commodities boom, copper prices increased worldwide,[39] increasing the incentive for criminals to steal copper from power supply and communications cables.[40][41][42]. Conductor types include non-metallic/non-metallic corrosion-resistant cable (two or more insulated conductors with a nonmetallic outer sheath), armored or BX cable (cables are surrounded by a flexible metal enclosure), metal clad cable, service entrance cable, underground feeder cable, TC cable, fire resistant cable, and mineral insulated cable, including mineral-insulated copper-clad cable. In the case of Copper the electrical conductivity is 0.596 10^6/cm ohm. In industry, this is very useful for plumbing pipework and joining busbars, which are vital elements of power distribution systems. [36], Copper is the preferred conductor material for underground transmission lines operating at high and extra-high voltages to 400 kV. This is not the case with copper. On a billiard table, this occurs when a ball strikes against another single ball, passing most of its energy onto the next ball. Electrical cables may be made more flexible by stranding the wires.

If a single ball strikes multiple other balls, each of those will carry only a fraction of the energy. [10], For certain applications, copper alloy conductors are preferred instead of pure copper, especially when higher strengths or improved abrasion and corrosion resistance properties are required. They do not shatter when they are dropped or become brittle when cooled below 0°C. ISBN 978-1-56032-992-3. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. Coaxial cables were extensively used in mainframe computer systems and were the first type of major cable used for Local Area Networks (LAN). U.S. Department of Energy, Material Science. Content by Bold & Pepper. Attempts to replace copper with aluminium in building wire were curtailed in most countries when it was found that aluminium connections gradually loosened due to their inherent slow creep, combined with the high resistivity and heat generation of aluminium oxidation at joints. The combination of all of these factors makes it easy for electricians to install copper wire.[17][21]. Copper has the highest electrical conductivity rating of all non-precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C. This copper is at least 99.90% pure and has an electrical conductivity of at least 101% IACS. The current rating of a conductor varies depending on the size, allowable maximum temperature, and the operating environment of the conductor. Structured wiring can also connect computers with printers, scanners, telephones, fax machines, and even home security systems and home entertainment equipment. This greater “wire fill” is a special advantage when a system is rewired or expanded. It does so by reducing the activation energy. 10 Examples of Electrical Conductors and Insulators, Table of Electrical Resistivity and Conductivity, Metallic Bond: Definition, Properties, and Examples, The Relationship Between Electricity and Magnetism, Understanding Electrical, Thermal, and Sound Conductors, The Basics: An Introduction to Electricity and Electronics. Van Der Burgt, Martin J., 2011, "Coaxial Cables and Applications". U.S. Department of Energy, Material Science. This, combined with its high ductility, medium strength, ease of joining and good resistance to corrosion, makes copper the first choice as a conductor for electrical applications.

Electric conductivity may be represented by the Greek letter σ (sigma), κ (kappa), or γ (gamma). This means that they were well suited to being used for tools and weapons. They have an attractive golden colour which varies with the copper content. They have a good resistance to tarnishing making them last a long a time. Sturgeon, W., 1825, Improved Electro Magnetic Apparatus. A particular cross-section of a stranded conductor gives it essentially the same resistance characteristics as a single-strand conductor, but with added flexibility.[22]. A low resistivity indicates a material that readily allows the flow of electric current. [5] Common applications include building wire, motor windings, electrical cables, and busbars.
