The minerals rutile (titanium dioxide) and ilmenite are used to extract titanium metal. In the earth's crust, titanium is abundant (iron-titanium oxide). Titanium is a strong, hard, and durable metal with a low density and great corrosion resistance. A wide range of titanium alloys, which are employed in applications ranging from very low to very high temperatures, enable these qualities. Weight reduction is achievable in a range of aerospace applications as well as other high-performance industries like medical, chemicals, and cars.
