Wire conductors for automobiles
First Claim
1. An electric wire conductor for use in automobiles made by twisting together a plurality of strands, said each strand before twisted having a tensile strength of 80-160 kgf/mm2 and a conductivity of 25% IACS or more, said conductor having a total sectional area of 0.05-0.30 mm2, a breaking load of more than 6 kgf, and an elongation at break not less than 2%, each of said strands comprising a surface layer made of copper or copper alloy and a core made of steel containing 0.15-0.85 percent of carbon, and at least one element selected from the group consisting of 0.05-0.3% Si, 0.3-1.9% Mn, 0.5-5.0% Ni, 0.2-2.0% Cr, 0.1-1.0% Mo, 0.01-0.2% Nb, 0.01-1.0% V, 0.001-0.006% B, 0.1-1.0% Be, 0.02-1.0% Al, 0.02-1.0% Ti, in the contents indicated above, a total of 0.05% or less of P and S as unavoidable impurities, and 0.3% or less of Cu.

Abstract
An electric wire conductor for use in automobiles made by twisting together a plurality of strands. Each of the strands has a surface layer made of copper or a copper alloy and a core made of steel containing 0.05-0.85 percent of carbon and other elements such as Si, Mn, Ni, Cr, Mo, Nb, V, B, Be, Al, or Ti and P, S and Cu. Each strand has a tensile strength of 80-160 kgf/mm2 before being twisted and a conductivity of 25% IACS or more. The conductor has a total sectional area of 0.05-0.30 mm2, a breaking load of more than 6 kgf, and an elongation at break not less than 2%.
