    Abstract: In a method for producing hot strips from a deformable lightweight steel which includes as main elements Fe, Mn, Si and Al, melt is cast close to its final dimension in a horizontal continuous strip casting installation under a protective gas to form a pre-strip between 6 and 20 mm, and the temperature of the pre-strip is adjusted after complete solidification and before the beginning of a hot-rolling process. The pre-strip is passed through a device under a protective gas for homogenization in concert with a selective maintenance of the temperature, cooling or heating, and subsequently subjected to a hot-rolling process having at least one pass with a total degree of deformation of at least 50%, and is then reeled as a hot strip following the cooling process. The hot-rolling process is executed in-line or in decoupled manner depending on the ratio of casting speed to rolling speed.

    Abstract: Provided are an aluminum alloy having high toughness and high electric conductivity, an aluminum alloy wire, an aluminum alloy stranded wire, a covered electric wire, a wire harness, and a process for production of an aluminum alloy wire. The aluminum alloy wire contains by mass 0.2 to 1.0% of Mg, 0.1 to 1.0% of Si, and 0.1 to 0.5% of Cu with the balance being Al and impurities and satisfies the relationship: 0.8?Mg/Si mass ratio?2.7. The Al alloy wire exhibits an electric conductivity of 58% IACS or above and an elongation of 10% or above. The Al alloy wire is produced via successive steps of casting, rolling, wire drawing, and softening treatment. Since the Al alloy wire has been subjected to softening treatment, the wire is excellent in toughnesses such as elongation and impact resistance, so that when used in a wire harness, the wire is inhibited from being broken in the neighborhood of a terminal in mounting the wire harness.
