Is Titanium A Rare Metal? What Are Its Properties And Uses?

Titanium is a transition metal and has been considered a rare metal for some time. Since the 1940s, titanium and its compounds have been widely used in aircraft, rockets, missiles, satellites, spacecraft, naval ships, military, medical and petrochemical fields. Because titanium has high melting point, high hardness, strong plasticity, small density, corrosion resistance and other advantages; Titanium looks like steel and has a silvery gray light translation. The strength of titanium is high, and the tensile strength of titanium alloy is 180kg/mm3. The characteristics of titanium are low density (4.51g/cm3), high hardness, high melting point (1675℃), high purity titanium has good plasticity, but when there are impurities become brittle and hard. At room temperature, titanium does not interact with chlorine, dilute sulfuric acid, dilute hydrochloric acid and nitric acid, but can be eroded by hydrofluoric acid, phosphoric acid and molten alkali. Titanium is easily dissolved in H2SO4, and the most outstanding property of titanium is its strong corrosion resistance to seawater. Titanium makes up about 0.42% of the total weight in the Earth's crust, ranking seventh in the metal world, with more than 70 minerals containing titanium. At present, titanium has been widely used in aircraft, rockets, missiles, satellites, spacecraft, ships, military industry, light industry, chemical industry, textile industry, medical treatment and petrochemical industry and other fields.
