Essex, Florida (PressExposure) July 20, 2009 -- Tungsten is one of the many kinds of metals today used for wedding rings. This is because of its known durability that even surpasses that of other materials such as gold and platinum. Aside from its use in tungsten jewelry, tungsten has also been one of the many metals known of their wide applications from high temperature applications to heavy machinery uses. Here are some of the known uses of tungsten other than the growing industry of tungsten jewelry.
For High Temperature Applications
Because it retains its strength at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications, such as material for the following:
* light bulb * cathode-ray tube * vacuum tube filaments * heating elements * rocket engine nozzles.
Its high melting point also makes tungsten suitable for aerospace and high-temperature uses such as electrical, heating, and welding applications, notably in the gas tungsten arc welding process (also called tungsten inert gas -TIG- welding).
For Heavy Duty Applications
The hardness and density of tungsten are applied in obtaining heavy metal alloys. A good example is high speed steel, which may contain as much as 18% tungsten. Superalloys containing tungsten, such as Hastelloy and Stellite, are used in turbine blades and wear-resistant parts and coatings. Applications requiring its high density include:
* heat sinks * weights * counterweights * ballast keels for yachts * tail ballast for commercial aircraft * ballast in race cars for NASCAR and Formula One.
It is an ideal material to use as a bucking bar for riveting, where the mass necessary for good results can be achieved in a compact bar.
In armaments, tungsten, usually alloyed with nickel and iron or cobalt to form heavy alloys, is used in kinetic energy penetrators as an alternative to depleted uranium but may also be used in cannon shells, grenades and missiles to create supersonic shrapnel.
Jewelers found that tungsten's density is the same as that with gold, which is why many jewelers today have come to consider it as the perfect alternative to gold and platinum. Though not as luxurious looking as other forms of materials such as white gold, platinum, palladium, tungsten jewelry gets its popularity with its durability. Its hardness makes it ideal for wedding rings which are usually prone to damages such as scratches due to daily wear. Another is that tungsten jewelry is known for its hypoallergenic nature which makes it perfect for people with sensitive skins.
