Estimating the term…
A wire for electric railways comprises a copper alloy which consists essentially, by weight percent, of 0.1 to 1.0% Cr, 0.01 to 0.3% Zr, 0.05 to 0.15% Sn, and 10 ppm or less O, and if required, further contains 0.01 to 0.1% Si, or 0.01 to 0.1% Si and 0.001 to 0.05% Mg, with the balance being Cu and inevitable impurities.
In a wire for an overhead line for an electric railway, the improvement comprising said wire being formed of a copper alloy consisting essentially, by weight percent, of 0.1 to 1.0% Cr, 0.01 to 0.3% Zr, 0.05 to 0.15% Sn, 0.01 to 0.1% Si, 10 ppm or less O, and the balance of Cu and inevitable impurities, and the wire having an electrical conductivity of at least about 80% IACS.
