PROBLEM TO BE SOLVED: To find material characteristics with strong correlation to bending workability and the contact pressure in the contact part when worked into a connector terminal regarding a titanium copper based alloy. SOLUTION: Regarding the titanium copper based alloy comprising 2 to 3.5 wt.% titanium, and the balance substantially copper with impurities, after final annealing, the difference between the compressive proof stress and tensile proof stress in a direction parallel to the rolling direction is controlled to≤50 MPa, and the difference between the compressive proof stress and tensile proof stress in a direction orthogonal to the rolling direction is controlled to≤200 MPa.
