  2. Copper-clad aluminium wire - Wikipedia

    en.wikipedia.org/wiki/Copper-clad_aluminium_wire

    A copper strip is formed into the shape of a cylinder, while it is being wrapped around an aluminum core and the edges of the copper strip are welded together. The assembly is then pulled through a die, where the cladded wire is squeezed and stretched while also improving the bonding between the copper and the aluminum core. [1]

    en.wikipedia.org/wiki/Aluminum_building_wiring

    Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...

  4. Aluminium–copper alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–copper_alloys

    Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium , iron , nickel and silicon ( AlCu(Mg, Fe, Ni, Si) ), often manganese is also included to increase strength (see aluminium-manganese alloys ).

  5. Aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy

    An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin , nickel and zinc .

  6. Electrical conductor - Wikipedia

    en.wikipedia.org/wiki/Electrical_conductor

    The main grade of copper used for electrical applications, such as building wire, motor windings, cables and busbars, is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C100140). If high conductivity copper must be welded or brazed or used in a reducing atmosphere, then oxygen-free high conductivity copper (CW008A or ASTM ...

  7. 2219 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/2219_aluminium_alloy

    2219 aluminium alloy is an alloy in the wrought aluminium-copper family (2000 or 2xxx series). It can be heat-treated to produce tempers with higher strength but lower ductility. The aluminium-copper alloys have high strength, but are generally less corrosion resistant and harder to weld than other types of aluminium alloys.

  8. Copper conductor - Wikipedia

    en.wikipedia.org/wiki/Copper_conductor

    An example of a copper alloy conductor is cadmium copper wire, which is used for railroad electrification in North America. [5] In Britain the BPO (later Post Office Telecommunications ) used cadmium copper aerial lines with 1% cadmium for extra strength; for local lines 40 lb/mile (1.3 mm dia) and for toll lines 70 lb/mile (1.7 mm dia).
