Titanium and its alloys are commonly used in the medical industry due to their excellent biocompatibility, strength, and corrosion resistance. They are frequently employed in medical implants, such as joint replacements, dental implants, and bone screws, as well as in prosthetics. These properties make titanium ideal for applications in which materials need to be in direct contact with human tissues without causing adverse reactions.
