<P>PROBLEM TO BE SOLVED: To provide a copper alloy sheet with a deformed cross section, which is a Cu-Fe-P-based copper alloy plate with a deformed cross section, and high press workability, and a method for producing the same. <P>SOLUTION: The copper alloy sheet with a deformed cross section has a thick part and a thin part arranged side by side in a width direction and has a composition comprising, by mass, 0.05-0.15% Fe, 0.015-0.050% P, 0.01-0.20% Zn and the balance being Cu and unavoidable impurities. When T1 and T2 represent the measured values for the thick part and the thin part, respectively, as measured by an EBSD method on a scanning electron microscope equipped with an electron backscattered diffraction imaging system, the ratio of orientation density of brass orientation (T1/T2) is 0.2-0.8, the ratio of orientation density of copper orientation (T1/T2) is 1.2-5.0, and the ratio of GOS (T1/T2) is 0.8-1.5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
