Abstract (en)
{Problems} To provide a Corson-based copper alloy sheet material which satisfies characteristics required of terminals and connectors, such as mechanical strength and bending property. {Means to solve} A copper alloy sheet material for electrical or electronic parts, which is composed of a copper alloy composition containing, in terms of mass%, any one or both of Ni or Co in an amount of 0.8 to 5%, and Si in an amount of 0.2 to 1.5%, with the balance being Cu and inevitable impurities, wherein an area ratio of grains having a deviation angle of less than 15° from the Cube orientation is controlled to less than 10%, and an area ratio of grains having a deviation angle of 15° to 30° from the Cube orientation is controlled to 15% or greater, and wherein the copper alloy sheet material has excellent mechanical strength and bending property.
