Title:
METAL CABLE AND ELECTRICAL WIRE
Document Type and Number:
WIPO Patent Application WO/2013/146757
Kind Code:
A1
Abstract:
The present invention provides high-strength and high-ductility metal cable and electrical wire in which the strength and ductility have been adequately increased. A metal cable (1) is manufactured, at a minimum, by performing a drawing process in which a metallic material (2) is drawn uniaxially. The metal cable (1) is provided with hardness distribution in which the hardness decreases from a center portion toward a specific circumferential portion in a specific radial direction in an axially perpendicular cross section, facilitating drawing of a softened circumferential portion, minimizing the incidence of cracks or the like, and improving tensile strength as well as ductility.
