Abstract (en)

[origin: EP3460081A2] The present invention is intended to improve bending workability of titanium copper for electronic components, and to provide a titanium copper for electronic components, which has excellent bending workability even when subjected to beating process, and to provide a method for manufacturing the same. One embodiment of the present invention is a titanium copper, comprising 2.0 to 4.5 mass% of Ti, and at least one element selected from the group consisting of Fe, Co, Ni, Cr, Zn, Zr, P, B, Mo, V, Nb, Mn, Mg, and Si in total of 0 to 0.5 mass% as a third element(s), and the rest consisting of copper and inevitable impurities, wherein in a crystal orientation analysis by EBSD measurement on the rolled surface, when an orientation difference of 5° or more is defined as a crystal grain boundary, a coefficient of variation of crystal grain size is 45% or less, and an area ratio of Cube orientation {001} <100> is 5% or less.
