    Abstract: The disclosed composite conductor has a steel component for supporting the weight of an annealed aluminum alloy -- steel composite overhead electrical conductor. Annealing the high strength aluminum alloy component improves service performance of the conductor by providing for sustained operation at high conductor temperatures without detriment to the mechanical properties thereof. The aluminum alloy component is specially formulated to have a tensile strength in the annealed condition which is substantially equivalent to the tensile strength of hard drawn EC aluminum. Consequently, the conductor of this invention has the strength of prior art cables having hard drawn aluminum components, while at the same time yielding high temperature operating characteristics of prior art cables having annealed aluminum components.

    Abstract: An aluminium alloy conductor having an electrical conductivity of at least fifty-seven percent (57%) based on the International Annealed Copper Standard having increased ultimate elongation, ultimate tensile strength, creep strength, thermal stability, bendability and fatigue resistance when compared to conventional aluminum conductors. The aluminum alloy conductor can contain intermetallic constitutents consisting of: iron and aluminum and optionally silicon in varying ratios, in a concentration produced by the addition of from more than about 0.99 to about 2.50 weight percent iron to an alloy mass containing less than about 98.83 weight percent aluminum, from more than about 0.18 to about 0.40 weight percent silicon, and trace quantities of conventional impurities normally found within a commercial aluminum alloy.

    Abstract: This disclosure relates to an aluminum alloy electrical conductor which contains from about 0.20% to about 1.60% by weight nickel, from about 0.30% to about 1.30% iron, optionally up to 2.00% of additional specified alloying elements, and the remainder aluminum with associated trace elements. The conductors are processed in a continuous operation which includes continuous casting, hot-rolling in the as-cast condition to form continuous rod, cold-working of the rod by drawing it through a series of wire-drawing dies, without preliminary or intermediate anneals, and thereafter annealing the wire to achieve a minimum electrical conductivity of 58% IACS, an ultimate tensile strenght of at least 12,000 psi, a yield strength of at least 8,000 psi and an elongation of at least 12% when measured as a No. 10 A.W.G. wire. The additional alloying elements are precisely controlled in order to facilitate the continuous processing of the cast bar without spitting and cracking of the subsequently rolled and cold-drawn rod.
