摘要： A titanium alloy material according to the present invention has higher strength than that of existing titanium alloy materials, is capable of performing cold rolling (coil rolling) excellently, and provided with machinability. The titanium alloy material according to the present invention reduces production costs since the titanium alloy material does not require an expensive alloy element. The titanium alloy of the present invention is composed of, in wt% per Al equivalent indicated as (Al + 100 (Oxygen) ): 3. 5-7. 2; Al: more than 1. 0-less than 4. 5%; O: less than 0. 60; of Fe equivalence indicated as (Fe+0. 5Cr+0. 5Ni+0. 67Co+0. 67Mn) in wt% and satisfied with more than 0. 8-less than 2. 0 of Fe; and of at least one element selected from a group composed of Cu: 0. 4-3. 0; Sn: 0. 4-10; and the remainder Ti and other inevitable impurities.
