COPPER ALLOY WIRE AND COPPER ALLOY WIRE MANUFACTURING METHOD |
| 摘要 |
This copper alloy wire consists of a precipitation strengthening type copper alloy containing Co, P, and Sn, wherein an average grain size of precipitates observed through cross-sectional structure observation immediately after performing an intermediate aging heat treatment is equal to or less than 15 nm and a number of precipitates having grain sizes of equal to or less than 5 nm is 10% or higher of a total number of observed precipitates, and the copper alloy wire is subjected to cold working and a final aging heat treatment after the intermediate aging heat treatment. |
