銅合金板材及びその製造方法
Document Type and Number:
Japanese Patent JP5158909
Kind Code:
B2
Abstract:
{Problems} To provide a copper alloy sheet material, excellent in bending property and mechanical strength, and suitable for lead frames, connectors, terminal materials, and the like in electrical/electronic equipments, for connectors, for example, to be mounted on automotive vehicles, and for terminal materials, relays, switches, and the like; and to provide a method of producing the same. {Means to solve} A copper alloy sheet material, containing at least one of Cr, Zr, and Ti in an amount of 0.05 to 1.0 mass% in total, with the balance being copper and unavoidable impurities, wherein an area ratio of Cube orientation {0 0 1} <1 0 0> is 5% or more and 70% or less, in crystal orientation analysis by an EBSD analysis, and wherein a Vickers hardness is 120 or more; and a method of producing the same.
