Titanium and its alloys are useful engineering materials because of their excellent resistance to corrosion in oxidizing environments and/or high strength-to-weight ratio. They also offer resistance to erosion by flowing solutions with entrained solids and good heat transfer characteristics.

Titanium alloys are metallic materials that are composed primarily of titanium, along with other elements such as aluminium, vanadium, iron, or nickel. These alloys are created by mixing titanium with small amounts of these alloying elements to enhance specific properties and characteristics.

These alloys are widely used in various industries, including aerospace, automotive, marine, medical, and sporting goods, where lightweight and high-strength materials are required.
