Abstract

Disclosed is a copper alloy containing 1.0% to 3.6% of Ni, 0.2% to 1.0% of Si, 0.05% to 3.0% of Sn, 0.05% to 3.0% of Zn, with the remainder including copper and inevitable impurities. The copper alloy has an average grain size of 25 μm or less and has a texture having an average area percentage of cube orientation of 20% to 60% and an average total area percentage of brass orientation, S orientation and copper orientation of 20% to 50%. The copper alloy has a KAM value of 0.8 to 3.0 and does not suffer from cracking even when subjected to U-bending. The copper alloy has excellent balance between strengths (particularly yield strength in a direction perpendicular to the rolling direction) and bending workability.
