Aluminum alloy wires with improved electrical conductivity and improved ultimate tensile strength are disclosed. The aluminum alloys include magnesium, silicon, and copper and are formed without a solution heat treatment. The aluminum alloy wires are useful as conductors for overhead transmission lines. Methods of making the aluminum alloy wires are further disclosed.

International Classification:
C22C 21/00
Abstract:
Improved 8000-series aluminum alloys exhibiting improved creep resistance and stress relaxation resistance are disclosed and are useful to form wires. The improved 8000-series aluminum alloys include a rare earth element. The electrical conductivity of the aluminum alloy is substantially unaffected by the addition of the rare earth element.

A conductive element of a cable or a wire is formed of an improved aluminum-zirconium alloy. The aluminum-zirconium alloy further includes an inoculant. The aluminum-zirconium alloy exhibits excellent ultimate tensile strength values and resistance to heat. Bonding wires formed from an improved aluminum-zirconium alloy exhibiting certain ultimate tensile strength values, fatigue resistance and/or creep rates are also described. Methods of forming cables and wires are also further disclosed.
High Temperature Creep Resistant Aluminum Superalloys
This invention relates to a series of castable aluminum alloys with excellent creep and aging resistance, high electrical conductivity and thermal conductivity at elevated temperatures. The cast article comprises 0.4 to 2% by weight iron, 0 to 4% by weight nickel, 0.1 to 0.6 or about 0.1 to 0.8% by weight zirconium, optional 0.1 to 0.6% by weight vanadium, optional 0.1 to 2% by weight titanium, at least one inoculant such as 0.07-0.15% by weight tin, or 0.07-0.15% by weight indium, or 0.07-0.15% by weight antimony, or 0.02-0.2% by weight silicon, and aluminum as the remainder. The aluminum alloys contain a simultaneous dispersion of A1Fe, A1X (X=Fe, Ni) and/or A1FeNi intermetallic in the eutectic regions and a dispersion of nano-precipitates of AlZrVTi(0≦x≦1, 0≦y≦1 and 0≦x+y≦1) having L1crystal structure in the aluminum matrix in between the eutectic regions. The processing condition for producing cast article of the present invention is disclosed in detail.
