The invention relates to an electrical transportation wire made of aluminum alloy comprising aluminum, zirconium and unavoidable impurities, characterized in that said alloy comprises at least 80 parts by weight of zirconium in the form of precipitates (AlZr) per 100 parts by weight of zirconium in said aluminum alloy.

Electrical transport wire made of an aluminum alloy, having high electrical conductivity

A process is provided for manufacturing a composite material with functionalized carbon nanotubes and a metal matrix. The arrangement also includes manufacturing an elongated electrically conductive element, and an electrical cable with such an elongated electrically conductive element.

Process for manufacturing a composite material

A method of manufacturing an elongated electrically conducting element having functionalized carbon nanotubes and at least one metal, includes the steps of mixing functionalized carbon nanotubes with at least one metal, to obtain a composite mixture, and forming a solid mass from the composite mixture from step (i). A solid element obtained from the solid mass from step (ii) is inserted into a metal tube, and the metal tube from step (iii) is deformed, to obtain an elongated electrically conducting element.

Method of manufacturing an elongated electrically conducting element

A strand of section of no more than 0.35 mmis provided having one or more electrical conductor wires, where each electrical conductor wire is constituted by an alloy of copper and tin. The tin content is not less than 1500 ppm and not more than 2500 ppm the oxygen content is not more than 400 ppm the inevitable impurities content is not more than 100 ppm and the balance of the content of the alloy is copper with the electrical conductor wire(s) being exempt from heat treatment during fabrication of the strand.
