Titanium: Metals
built 282 days ago
Titanium is a very lightweight metal with great strength. Because it has great resistance to acidity, it doesn't change its appearance over time like many other metals. Wearing a titanium magnetic bracelet, you don’t have to worry about damaging your jewelry while participating in outdoor activities. You can wear your titanium bracelet to the hot tub or swimming pool and not have to worry about it getting damaged by chlorine. For someone with sensitive skin that usually cannot wear jewelry, titanium might be the only choice. For years titanium has been known for its compatibility with the human body and has been widely used as a surgical replacement for bones and hips.

Titanium is the world's fourth most abundant structural metal. It is found in North America, South America, Europe, Africa and Australia in the forms of ilmenite, rutile and other ores. The most widely used means of winning the metal from the ore is the Kroll process which uses magnesium as a reducing agent. Sodium is ... used as a reducing agent by some producers.

Titanium rings provide stylish grey tones similar to platinum, but are more attractive in price. With its rich luster, many designers offer cutting edges titanium rings. Titanium is at the forefront in the designer jewelry community. No other metal has experienced such a dramatic rise in popularity as titanium. Leave gold and silver to the Jones, Titanium Rings are for those who know luxury, style and liken themselves to none other than Greek gods.

Titanium metal is produced commercially by reducing TiCl4 with magnesium, a process developed in 1946 by William Justin Kroll. This is a complex and expensive batch process, but a newer process called the "FFC-Cambridge" method may displace this older process. This method uses the feedstock titanium dioxide powder (which is a refined form of rutile) to make the end product which is a continuous stream of molten titanium suitable for immediate use in the manufacture of commercial alloys.

Titanium was discovered by a British mineralogist, Gregor Williams, in 1791. In 1795, a German chemist and mineralogist, Martin H. Klaproth, named it Titanium. This was derived from the Titans of Greek mythology, characters owning extreme power and superior strength. Titanium wasn't widely used until the early 20th century because the technology wasn't available to separate it from Titanits compounded material. William Kroll, a refugee from Luxembourg, invented a process that allowed production of metallic titanium to be available. The United States Bureau of Mines used the Kroll process to produce metallic titanium and received financial aid for its production.

Titanium metal is used in automotive applications, particularly in automobile or motorcycle racing, where weight reduction is critical while maintaining high strength and rigidity. The metal is generally too expensive to make it marketable to the general consumer market, other than high end products. Late model Corvettes have been available with titanium exhausts,[42] and racing bikes are frequently outfitted with titanium mufflers. Titanium alloy is used for the connecting rods in the engine of the 2006 and later Corvette Z06. Other automotive uses include piston rods and hardware (bolts, nuts, etc.).
