Titanium is one of the elements with high abundance in the crust, ranks ninth with 0.64% proved content in the crust. Titanium has low density, high specific strength and corrosion resistance. Titanium and titanium alloys are widely used in aerospace, petrochemical, electric power, seawater desalination and other industries, below are different titanium and titanium alloys and related Chemical compositions,
