<p>A copper base alloy for electronic parts containing 2.0 to 4.0 mass % of Ti and 0.05 to 0.50 mass % of one or more of Fe, Co, Ni, Si, Cr, V, Nb, Zr, B and P, wherein the content of other impurity elements is 0.010 mass % or less in total, and the content of each of C and O is 0.010 mass % or less. This copper base alloy can be used without heat treatment after its press working into a part of a connector or the like; or can be also used in a state in which the alloy is subjected to a specific heat treatment so as to be improved in spring characteristics after its press working.</p> |
