Titanium alloy material excellent in scale deposition inhibiting property and formability and a method of producing the same, as well as a heat exchanger or a seawater evaporator

摘要

The titanium alloy material of the invention is excellent in a deposition inhibiting property of scales mainly comprising calcium carbonate contained in water and exhibits an excellent formability during manufacture of a heat exchanger or the like. The titanium alloy material of the invention contains P in an amount of 0.005 to 0.30% (mass% here and hereinafter) and Sn in an amount of 0.01 to 3.0%, with the balance of Ti and unavoidable impurities. Further, in a case where the titanium alloy material contains one or more elements selected from the group consisting of Cu, Fe, and Ni, they may satisfy the following formula (1):
in which Cu, Fe, Ni and Sn each represent the content (mass%) of the respective elements in the titanium alloy in the formula (1).
