    • The present invention provides a high strength titanium alloy useful as a material for products such as ornaments, products such as ornaments made of the titanium alloy, and a method for producing the products using the titanium alloy as a material. The high strength titanium alloy is capable of attaining high machinability, and the product made of the titanium alloy is excellent in beauty and decorativeness while being hard to made flawed or concaved. According to the present invention, the titanium alloy includes iron of 0.20 to 0.8 mass percent and oxygen of 0.20 to 0.6 mass percent, or iron of 0.2 to 1.0 mass percent, oxygen of 0.15 to 0.6 mass percent and silicon of 0.20 to 1.0 mass percent, with the balance of titanium and inevitable impurities. A method for producing a product using the titanium alloy as a material includes a steps of hot forging the titanium alloy at a temperature of (.beta.-transformation temperature -200.degree. C.) or higher, and then cooling it, thereby giving a high strength to the product.
