Abstract
A copper alloy sheet material, having an alloy composition containing at least one of Ni and Co in an amount of 1.80 to 8.00 mass % in total, Si in an amount of 0.40 to 2.00 mass %, and at least one element selected from the group consisting of Sn, Zn, Ag, Mn, P, Mg, Cr, Zr, Fe, and Ti in an amount of 0.000 to 2.000 mass % in total, with the balance being copper and unavoidable impurities, wherein the orientation density of the {121}<111> orientation is 6 or less, and the orientation density of the {110}<001> orientation is 4 or more; and wherein the density of grains having the {110}<001> orientation is 0.40 grains/μm2 or more; a connector using thereof; and a method of producing the copper alloy sheet material.
