Titanium is widely used in aerospace applications due to its high strength-to-density ratio and excellent resistance to extreme temperatures. It is a key material in the construction of jet engines, airframes, and spacecraft, where lightweight and durability are critical. In the medical field, titanium is used for implants such as hip joints, dental prosthetics, and bone fixation devices because of its biocompatibility and ability to integrate with human bone. The chemical industry uses titanium in equipment exposed to corrosive substances, especially in the production of chlorine and caustic soda, where titanium's corrosion resistance is highly valuable. Titanium dioxide, a compound derived from titanium, is extensively used as a white pigment in paints, coatings, plastics, paper, and cosmetics due to its brightness and high refractive index. It is also used in sunscreens for its ability to block ultraviolet radiation. Additionally, titanium is used in the automotive industry to reduce vehicle weight and improve fuel efficiency, particularly in high-performance and racing engines. It is also found in sporting goods like golf clubs, bicycle frames, and backpacking equipment for the same lightweight and strength advantages.
