Titanium alloys are used in aircraft (including helicopters), armor plating, naval ships, spacecraft and missiles. [23] It is also used in cement, in gemstones, as an optical opacifier in paper,[73] and a strengthening agent in graphite composite fishing rods and golf clubs. Titanium dioxide nanoparticles are widely used in electronics and the delivery of pharmaceuticals and cosmetics. Star sapphires and rubies get their asterism (star-forming shine) from the presence of titanium dioxide impurities. [7][8] For these applications, titanium is alloyed with aluminium, zirconium, nickel,[75] vanadium, and other elements to manufacture a variety of components including critical structural parts, fire walls, landing gear, exhaust ducts (helicopters), and hydraulic systems. Titanium is a core material in the components of the world’s lightest bicycle, which weighs only 6 lbs.! [33] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs Scale),[34] and is often used to coat cutting tools, such as drill bits. [82] Other applications include ultrasonic welding, wave soldering,[83] and sputtering targets. [35] It is also used as a gold-colored decorative finish and as a barrier metal in semiconductor fabrication. Titanium is widely distributed and constitutes 0.44 percent of the Earth’s crust. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Certain titanium alloys (e.g., Beta C) achieve tensile strengths of over 1,400 MPa (200,000 psi). Titanium alloys do not fatigue easily, are strong and are resistant to corrosion so they are perfect for use in the above items. Considering an average adult bike weighs 30 lbs.

. Titanium isopropoxide is used in the synthesis of chiral organic compounds via the Sharpless epoxidation. An individual using titanium dental implants can undergo MRI examination as these implants are not magnetic.

[17], Titanium is not as hard as some grades of heat-treated steel; it is non-magnetic and a poor conductor of heat and electricity. Its high strength to weight ratio also makes it the perfect choice for surgical instruments and other medical devices. Titanium is used for the surgical instruments used in image-guided surgery, as well as wheelchairs, crutches, and any other products where high strength and low weight are desirable. About 6.0 and 0.7 million tonnes of those minerals were mined in 2011, respectively. Many backpackers use titanium equipment, including cookware, eating utensils, lanterns, and tent stakes. [6] Titanium is often alloyed with aluminium (to refine grain size), vanadium, copper (to harden), iron, manganese, molybdenum, and other metals. In this process, the chlorine gas is passed over a red-hot mixture of rutile or ilmenite in the presence of carbon. As an example, the A380 Airbus uses approximately 70 tons of Titanium for the aircraft structure and fittings. The SR-71 “Blackbird” war plane was the first aircraft to use Titanium Alloys extensively in its structure and skin. [75], Titanium is used in the walls of the Juno spacecraft's vault to shield on-board electronics. Titanium tetrachloride is also used to make titanium dioxide, e.g., for use in white paint. An early use in jet engines was for the Orenda Iroquois in the 1950s. [19] The remaining grades are alloys, each designed for specific properties of ductility, strength, hardness, electrical resistivity, creep resistance, specific corrosion resistance, and combinations thereof. [48] Eight years later he refined this process with magnesium and even sodium in what became known as the Kroll process. If individual plates of the same weight were made from Titanium, Copper and Stainless Steel, the Titanium Plate would be double the size of the copper, and 75% larger than the Stainless Steel. It is also a good reflector of infrared radiation and so is used in solar observatories where heat causes poor visibility. [8] Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and titanium trichloride (TiCl3), which is used as a catalyst in the production of polypropylene. Via the Kroll process, TiCl4 is used in the conversion of titanium ores to titanium metal.
