Soft dilute copper alloy material, soft dilute copper alloy wire, soft dilute copper alloy plate, soft dilute copper alloy twisted wire and cable using these

摘要

PROBLEM TO BE SOLVED: To provide: a soft-dilute-copper-alloy material having high electrical conductivity and long bending life even in a soft copper material; a soft-dilute-copper-alloy wire, soft-dilute-copper-alloy sheet and soft-dilute-copper-alloy stranded wire; and also to provide a cable, coaxial cable and composite cable using them.;SOLUTION: The soft-dilute-copper-alloy wire contains Ti of 4-55 ppm by mass and the balance of Cu, and is characterized in that the average crystal grain size is 20 μm or less in the surface layer up to a depth of at least 50 μm from the surface.;COPYRIGHT: (C)2012,JPO&INPIT
