Abstract:
A titanium alloy product according to the present invention: has a strength level higher than that of an existing titanium alloy product; can be successfully cold rolled (coil rolled); and is also provided with workability. In the titanium alloy product according to the invention, expensive alloy elements are not essentially required, and hence cost can be suppressed. The titanium alloy product according to the invention includes Al equivalent represented by (Al+10O (oxygen)): 3.5 to 7.2% (% by mass, the same hereinafter), Al: more than 1.0% and 4.5% or less, O: 0.60% or less, Fe equivalent represented by (Fe+0.5Cr+0.5Ni+0.67Co+0.67Mn): 0.8% or more and less than 2.0%, and one or more elements selected from the group consisting of Cu: 0.4 to 3.0% and Sn: 0.4 to 10%, in which the balance is Ti and unavoidable impurities.
