<P>PROBLEM TO BE SOLVED: To provide a soft dilute copper alloy material having high conductivity, capable of reducing half-softening temperature and having improved bending life in a soft copper material. <P>SOLUTION: A soft dilute copper alloy wire includes 12 mass ppm or less of sulfur, >2 mass ppm of oxygen, 4-55 mass ppm of Ti, and the balance of copper. In the soft dilute copper alloy wire, an electrical conductivity is 98% IACS or more, a half-softening temperature is 148°C or below, and an average crystal grain size in a surface layer at least up to a depth of 50 μm from a surface is 20 μm or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
