The titanium ring is a ring or jewelry band primarily made of titanium. The actual composition of titanium can vary, such as "pure commercial" (99.2% titanium) or "plane grade" (especially, 90% titanium, 6% aluminum, 4% vanadium), and titanium rings often made in combination with others. materials, such as gemstones and traditional metal jewelry. Even with this variety of compositions and materials, a titanium ring is usually referred to as such if it contains a certain amount of titanium.
The rings made of titanium are a modern phenomenon, becoming widely available in the market around the 1990s. The titanium rings offer several unique properties: they are biocompatible (hypoallergenic), lightweight, corrosion resistant, and have the highest strength-to-weight ratio of any crystalline metal.

History
Titanium was discovered in Cornwall, England, in 1791 by William Gregor. It was also discovered around the same time by the Hungarian mineral expert Franz-Joseph MÃÆ'üller von Reichenstein, and then in 1795 by the German chemist Martin Heinrich Klaproth - who gave the name titanium, a reference to the Greek mythology Titan.
However, it was not until after 1932 that commercial use for titanium became possible, because of the method established by William Justin Kroll. Kroll found a way of reducing titanium tetrachloride (TiCl 4 ) into its metal form. The process is still in use today for commercially produced titanium.
The cost of titanium rings can be very high. It's as if the process of extracting titanium from various ores is exhausting and expensive. Although it is expensive as an engineering material, it is much cheaper than the usual precious metal jewelry, even silver. In early 2014, no price for pure titanium or commercial alloys generally exceeded US $ 10 per pound. The process of making titanium rings is expensive, and is necessary because the metal is almost impossible to make by rolling or soldering in a way that silver, gold and even platinum are formed.
It is not known who first made titanium into a ring or other jewelry. The titanium mating ring is used as a small plot point in the 1989 science fiction film and The Abyss novel. Titanium began to appear on the open market around the 1990s. Since 2000, the availability of titanium rings has become a large scale, with most online jewelry and brick and mortar stores likely to carry titanium-based rings as part of their inventory. Many outlets now specialize exclusively in the design and sale of titanium rings.

Construction
The titanium ring is built using solid rods, titanium tubes or sheets, which are cut into the desired shape and size of the ring. The metal can be worked by using the same equipment and through the same engineering process as stainless steel. The usual jewelry making techniques of rolling and soldering are impractical for titanium, although they can be made by welding in an inert atmosphere using, for example, laser welders.
Properties
Titanium has become popular as a jewelry because of its unique properties. Titanium is biocompatible (often referred to as hypoallergenic), or non-toxic to the human body. Similarly, the titanium ring will not react with the wearer suffering from allergies to other jewelry materials.
It is highly resistant to most corrosion causes, including sea water, aqua regia, chlorine (in water), and some acids. It dissolves in concentrated acids, however. The titanium ring is a practical jewel for those who regularly swim in the sea or chlorinated pools. This is in contrast to some of the traditional jewelry materials, such as silver, brass, and bronze, which tend to tarnish or other damage.
Titanium rings generally have higher fatigue resistance and strength to weight ratio than most other metals.
The titanium ring is difficult but it is possible to resize. The number of reductions and increases is limited.
They are only slightly more difficult to cut in an emergency than a gold ring; titanium is proportional to steel in its resistance to sawmill.
Anodizing
Anodizing of titanium rings is a process by which oxide films form on the surface of titanium through an electrolytic process to create color. In the case of titanium rings, this process is done after the machine is formed. Oxidation changes the color of regular titanium (generally silver, depending on composition and processing) and improves corrosion resistance. The anodizing process is very simple to do: the piece is dipped in electrolyte, the popular cola is used, and the DC voltage, about 100V, is applied. The voltage controls the thickness, and thus the color, of the anodization.
The dye does not need anodized titanium. The color produced on the titanium ring depends on the thickness of the oxide layer, which is determined by the anodizing stress. The image on the left shows the range of color spectra that can be achieved by anodization. The colors, which are just different wavelengths of light, arise from constructive interference between reflected light from the surface of the oxide layer and reflected light from the metal surfaces below.
titanium composition
Titanium can be mixed with many other metals to enhance or change the properties of titanium. The most common alloy partners for titanium are aluminum, vanadium, iron, molybdenum and copper. Each changes the properties of titanium for various purposes - for example, copper can be used to solidify titanium.
One of the most common compositions for titanium rings is known as the "plane class" (also referred to as titanium 6AL-4V or 6-4), since the composition is notable for its use in aircraft construction (however, it is also used for medical, marine and chemical processing purposes). It is a mixture of 6% aluminum, 4% vanadium and titanium 90% (as well as trace amounts of iron and oxygen, max 0.25% and 0.2% respectively), and is one of the other strongest and lightest known compositions. Aircraft grade titanium is often used in the manufacture of titanium rings due to its favorable and appropriate properties (compared to other titanium compositions), as well as its extensive commercial availability.
Inlays
Inlay is the result of combining or two or more metals into one ring. It does not get confused with the blend. The inlaying process involves destroying the metal into a channel, which is then trapped under pressure. On the ring, this usually produces a metal that sits side by side on the surface - for example, a gold strip that flows in the center of a titanium ring.
The purpose of the inlays is to allow the various metals in titanium rings to become visible distinguishable.
Styles
Titanium rings have been made into a variety of styles that can be distinguished over the short history of their development as jewelry. Some of these styles are:
Classic
The titanium ring style called "classic" is generally made into a simple oval or circle with a smooth, glossy finish. In addition to ordinary machines, no external techniques or equipment are used in its production.
Mokume-gane
Mokume-gane provides a titanium ring on a wood fiber display. This is a technique for forging Japan (also the beginning of the European Middle Ages) which was applied to the Samurai sword in the 17th century. It takes a great skill from the blacksmith; although current modern processes, such as controlled atmosphere and temperature controlled furnaces make this technique more accessible.
Sable
Sable gives a soft silk appearance.
Frost
Frozen titanium rings have a frozen appearance - specifically, frozen condensation that appears on goods that have been placed in the freezer.
