PROBLEM TO BE SOLVED: To provide a titanium alloy material for exhaust system components excellent in oxidation resistance and formability, and to provide an exhaust apparatus using the alloy material. SOLUTION: The titanium alloy material contains 0.5 to 1.8% Cu, 0.1 to 0.6% Si and≤0.1% oxygen, and the balance Ti with inevitable impurities. Alternatively, the titanium alloy material further contains 0.1 to 1.0% Nb, and the balance Ti with inevitable impurities. In the exhaust apparatus, one or more components selected from an exhaust manifold, an exhaust pipe, a catalyst and a muffler are composed of the titanium alloy material. COPYRIGHT: (C)2009,JPO&INPIT
