Abstract: 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.

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.

Abstract: Aluminum-zirconium and aluminum-zirconium-lanthanide superalloys are described that can be used in high temperature, high stress and a variety of other applications. The lanthanide is preferably holmium, erbium, thulium or ytterbium, most preferably erbium. Also, methods of making the aforementioned alloys are disclosed. The superalloys, which have commercially-suitable hardness at temperatures above about 220° C., include nanoscale Al3Zr precipitates and optionally nanoscale Al3Er precipitates and nanoscale Al3(Zr,Er) precipitates that create a high-strength alloy capable of withstanding intense heat conditions. These nanoscale precipitates have a L12-structure in ?-Al(f.c.c.) matrix, an average diameter of less than about 20 nanometers (“nm”), preferably less than about 10 nm, and more preferably about 4-6 nm and a high number density, which for example, is larger than about 1021 m?3, of the nanoscale precipitates.

Abstract: 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 A16Fe, A13X (X=Fe, Ni) and/or A19FeNi intermetallic in the eutectic regions and a dispersion of nano-precipitates of Al3ZrxVyTi1?x?y (0?x?1, 0?y?1 and 0?x+y?1) having L12 crystal 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.
