Four years later, Martin Heinrich Klaproth rediscovered the element in the mineral rutile and named it titanium. However, the metal was not isolated until 1910.
Titanium is present in meteorites and in the sum.
It is almost always present in igneous rocks, in the ash of coal, in plants and in the human body. Titanium has a low density, good strength, is easily fabricated, and has excellent resistance to corrosion. Because titanium is strong and lightweight, it is used in metallic alloys and as a substitute for aluminum. It is used in aircraft for fire walls, outer skin, landing-gear components, hydraulic tubing and engine supports. The Mercury, Gemini and Apollo capsules were made largely of titanium.
