Title:
COPPER ALLOY WIRE ROD MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/110037
Kind Code:
A1
Abstract:
The purpose of the present invention is to optimize the aggregate structure of a copper alloy wire rod material, effectively manifest characteristics that result from controlling the aggregate structure, and provide a copper alloy wire rod material with excellent strength and fatigue resistance and a production method therefor. The copper alloy wire rod material has an alloy composition containing 3.0-25.0 mass% of Ni and 0.1-9.5 mass% of Sn, also containing specified amounts of at least one component selected from the group consisting of Fe, Si, Mg, Mn, Zn, Zr and Pb, the balance Cu and unavoidable impurities, and having an aggregate structure. The copper alloy wire rod material is characterized in that for the aggregate structure, the average value of the orientation density within ±15° of the (100) plane orientation of the inverse pole figure of the longitudinal direction of the wire rod material, obtained by performing aggregate structure analysis using the electron backscatter diffraction (EBSD) method in a cross-section perpendicular to said longitudinal direction, is in the range of 5.0 and above, and the average value of the orientation density within ±15° of the (111) plane orientation of the inverse pole figure is in the range of 5.0 and above.
