Title:
COPPER ALLOY SHEET MATERIAL, CONNECTOR, AND PRODUCTION METHOD FOR COPPER ALLOY SHEET MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/099098
Kind Code:
A1
Abstract:
Provided is a copper alloy sheet material which is suited for use in a connector or the like, and which simultaneously exhibits a high yield strength, good bending workability and good electrical conductivity. Specifically provided is a copper alloy sheet material having a composition that contains a total of 1.80-8.00 mass% of one or more of Ni and Co, 0.40-2.00 mass% of Si, and a total of 0.000-2.000 mass% of at least one element selected from the group consisting of Sn, Zn, Ag, Mn, P, Mg, Cr, Zr, Fe and Ti, with the remainder being copper and inevitable impurities, wherein the orientation density of the {121}<111> component is 6 or less, the orientation density of the {110}<001> component is 4 or greater, and the concentration of crystal grains having the {110}<001> component is 0.40 crystals/μm2. Also provided are a connector using the copper alloy sheet material, and a production method for the copper alloy sheet material.
