Titanium was first isolated in 1791 by William Gregor , a clergyman and amateur geologist in Cornwall, England. However, it was not purified until 1910, and was not refined and produced in commercial quantities until the early 1950s. Most people think of titanium as a rare metal but it is not. Titanium is a common metal although relatively costly to produce. Titanium metal is physiologically inert and will not produce skin irritation or allergy.
Titanium is immune to corrosive attack by salt water or marine atmospheres.
It also exhibits exceptional resistance to a broad range of acids, alkalis, natural waters and industrial chemicals. Titanium offers superior resistance to erosion, cavitation and impingement attack. Titanium is at least twenty times more erosion resistant than the copper nickel alloys. Considering all its various and forthcoming applications, titanium is the metal of the future. Its tensil strength goes up to 180,000 psi.
