摘要
The present invention relates to copper alloys to have high-intensitive and excellent bendability, separately includes 0.01 to 3.0% mass parts, 0.01 to 0.4% piece of P of Fe and 0.1 to 1.0% mass M g, remaining is Cu and inevitable impurity, whereinIn grain diameter measurement by crystal orientation analysis method, wherein electron backscattered modular system is mounted on field emission scanning electron microscope, average grain diameter describes 6.5 m or less, the standard deviation partial size with mean as described below are 1.5 m or smaller: wherein when n indicates to indicate measured value in the grain diameter measurement and x of crystal grain, average grain diameter is (Σ x)/n, and the standard deviation partial size with mean is [n Σ x2-dichloro (/) 2] Σ x [n/ (n-1) 1/2].
