PROBLEM TO BE SOLVED: To provide a titanium alloy material having excellent scale adhesion-suppressing property based on calcium carbonate included in water and expressing excellent moldability in manufacturing a heat exchanger, etc.SOLUTION: A titanium alloy material contains P:0.005 to 0.30 mass% and Sn:0.01 to 3.0 mass% and the balance Ti with inevitable impurities. Further when the titanium alloy material includes one or more chemical elements selected from a group consisting of Cu, Fe and Ni, following formula (1) is satisfied: Cu+4.9Fe+1.3 Ni+0.5Sn≤1.6 (1), where Cu, Fe, Ni and Sn show the content (mass%) of each element in the titanium alloy material. |
