摘要： A method for producing a hot-dip aluminum-coated steel wire, including dipping a steel wire in molten aluminum, and drawing up the steel wire from the molten aluminum, wherein at the time of drawing up the steel wire from the molten aluminum, a stabilization member is contacted with a surface of the molten aluminum and the steel wire at the boundary between the steel wire and the surface of the molten aluminum, a nozzle having a tip end of which inside diameter is 1 to 15 mm is disposed so that the tip end is positioned at a place away from the steel wire by a distance of 1 to 50 mm, and an inert gas having a temperature of 200 to 800° C. is blown out from the tip end to the boundary at a volume flow rate of 2 to 200 L/min.

摘要： Provided is (i) a hot-dip Al-based alloy-coated steel sheet which includes a coated layer having a surface on which fine spangles are stably and sufficiently formed and which has a beautiful surface appearance due to the fine spangles thus formed on the surface of the coated layer, and (ii) a method of producing such a hot-dip Al-based alloy-coated steel sheet. The hot-dip Al-based alloy-coated steel sheet includes: a substrate steel sheet; and a hot-dip aluminum-based alloy coated layer which is formed on a surface of the substrate steel sheet and which contains boron at an average concentration of not less than 0.005 mass % and contains potassium at an average concentration of not less than 0.0004 mass %.

摘要： A crimp terminal includes an F-type crimp portion and a C-type crimp portion. The F-type crimp portion has first and second barrel tabs, preferably with an identical length, for crimping a tip end of a complex stranded wire. The F-type crimp portion is adapted to have distal ends of the first and second barrel tabs put together and pushed into the tip end of the complex stranded wire to be crimped. The C-type crimp portion has a third barrel tab for crimping the complex stranded wire. The third barrel tab is wound in a C-form on an outer periphery of the complex stranded wire to be crimped. The arrangement provides a crimp terminal and an electric wire with crimp terminal, that prevents or reduces increases in retained resistance at a crimp portion, and can also prevent an electric wire from slipping out of a crimp terminal.

摘要： A method of producing an Al plated steel wire comprises a first step of continuously immersing a material steel wire formed of a steel core into a molten Al plating bath and then withdrawing the material steel wire to a gas phase space. The material steel wire plated with a plating metal is brought into contact with a contact member at the plating bath rising portion to produce the Al plated steel wire, the Al plated steel wire having an average diameter DA (mm) and a minimum diameter DMIN (mm) in the longitudinal direction of the wire satisfying the following expression (1) (DA−DMIN)/DA≤0.10, (1). The Al plated steel wire is then wound.
