Title:
WIRE CONDUCTOR AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/053897
Kind Code:
A1
Abstract:
A wire conductor excellent in tensile strength, elongation at break, impact resistance, electrical conductivity, and fatigue properties; and a process for producing the conductor. The wire conductor is made of aluminum alloy filaments twisted together, the filaments containing 0.3-1.2 mass% silicon and containing magnesium in such an amount as to result in an Mg/Si of 0.8-1.8, with the remainder substantially being aluminum and incidental impurities. The wire conductor has a tensile strength of 240 MPa or higher, elongation at break of 10% or higher, absorbed impact energy of 8 J/m or higher, and electrical conductivity of 40% IACS or higher. The production process comprises twisting aluminum alloy filaments having that composition to form a twisted wire and then subjecting this twisted wire to solution heat treatment, quenching, and aging heat treatment. The temperatures for the solution heat treatment and aging heat treatment are preferably 500-580°C and 150-220°C, respectively. Heating for the solution heat treatment preferably is high-frequency heating.
