Titanium in its element form is a lustrous transition metal with a silver colour, low density and high strength. It is the 9th most abundant element in the earth’s crust. It occurs naturally in Ilmenite (92-98%), rutile (35-60%) and Titanomagnetite (2-20%) minerals, among others, in the oxide form. Most of these minerals are, however, processed into synthetic raw material in the form of TiO2 slag due to the presence of iron and/or other elements of value.
When Titanium added to steel, it gives the corrosion resistance property and because it is very light (half the density of steel) and strong, it makes very light but strong titanium-steel alloys, useful in spacecraft and aircraft applications.
In the 4th Industrial Revolution, Titanium powder is the dominating metal powder in 3D Printing (3DP) or Additive Manufacturing. It is widely used in aerospace industry, automobile industry, medical and pharmaceutical sectors.
