摘要

PPROBLEM TO BE SOLVED: To provide a soft-dilute-copper-alloy material, a soft-dilute-copper-alloy wire, a soft-dilute-copper-alloy sheet, a soft-dilute -copper-alloy stranded wire, and a cable, a coaxial cable and a composite cable using the same. PSOLUTION: The soft-dilute-copper-alloy material contains: copper and additional elements selected from the group consisting of Ti, Mg, Zr, Nb, Ca, V, Ni, Mn and Cr, and the balance of inevitable impurities. The soft-dilute-copper-alloy wire is characterized in that the average crystal grain size is 20 μm or less in the surface layer up to a depth of 50 μm from the surface. PCOPYRIGHT: (C)2011,JPO&INPIT
