摘要

A soft be provided, which is diluted copper alloy material, a wire of a soft diluted copper alloy, a film made of a soft diluted copper alloy, a stranded wire of a soft diluted copper alloy, and a using the cable, the coaxial cable and cable gemischtadriges. The disclosed soft diluted copper alloy material comprises: copper; at least one additional element selected from the group consisting of ti, mg, zr, nb, ca, v, ni, mn and cr; and the remainder unavoidable impurities. The soft diluted copper alloy material is characterized in that the average particle size of not more than 20 μm in the surface layer to a depth of 50 μm of the surface is.
