Abstract: The invention concerns electrical conductors of Al-Fe alloys containing from 0.5 to 5% of Fe. Conductors having a highly fibered structure which are stable up to 350.degree. C and have a range of mechanical and electrical characteristics which are remarkable and an excellent surface state are obtained by press drawing of granules of Al-Fe alloys obtained by centrifugal spraying of the liquid metal. Application to electrical conductors in the form of wires, cables and various shaped sections such as flat sections and strips which may be flexible or rigid.

Abstract: The invention relates to the field of electrical conductors of aluminum-based alloys. The invention comprises subjecting a wire rod of Al-Mg-Si alloy to continuous quenching, tepid drawing and continuous artificial aging. The invention makes it possible to produce wires and cables for overhead lines with mechanical and electrical characteristics substantially exceeding present standards.

Abstract: The invention relates to improved electrical conductors of aluminum-based alloys containing from 0.15 to 0.35% of iron, from 0.30 to 0.70% of silicon, from 0.30 to 0.80% of magnesium, and up to 0.40% of copper. These conductors are obtained by drawing wire rod at a temperature of from 110.degree. to 180.degree. C, followed by artificial aging at a temperature in the range from 130.degree. to 240.degree. C. The invention may be applied in the manufacture of overhead cables for carrying power over long distances.
