Titanium copper alloy having excellent punchability

摘要

A copper material alloy comprising 2.0 to 4.0 weight % of Ti and 0.05 to 0.50 weight % of Fe wherein; inevitable impurities have an amount of 0.01 weight % or less in total; and the ratio of X ray diffraction intensity of the alloy satisfies I(311)/I(111)>=0.5. The copper alloy of the present invention has improved punchability and excellent bendability.
