Titanium Prava and Simran History ● ● ● Titanium was discovered in 1791 by the Reverend William Gregor, an English pastor. First produced by Matthew A. Hunter, an American metallurgist, in 1910. It is the ninth most abundant element in the earth’s crust. Titanium makes up 0.57% of the earth’s crust. Titanium metal Reverend William Gregor Material/ Uses ● ● Titanium is a strong, light metal. It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and 60% heavier than aluminum. ● Used in various ways; propeller shafts, rigging and other parts of boats that are exposed to the sea. ○ Even used in sunscreen. ● Titanium & titanium alloys is a mixture between titanium and other elements ○ used in airplanes, missiles, rockets, where strength (low weight and resistance to high temperatures are important).
