3724 Ashwood Drive Essex, Florida (PressExposure) May 14, 2009 -- There are many kinds of precious metals used today in jewelry. These include gold, silver, platinum and palladium. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is most widely traded. Other than these metals, one of the most popular types of precious metal currently used today in jewelry, particularly with wedding rings, is tungsten. So what is tungsten? Tungsten
Before the availability of tungsten jewelry, tungsten was first used for industrial means. Itâs known to have the highest melting point of all the non-alloyed metals and the second highest of all the elements after carbon. Because it retains its hardness at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications, such as in light bulbs, cathode-ray tubes, vacuum tube filaments, heating elements, and rocket engine nozzles.
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. These are the obvious reasons why tungsten is used now in most jewelry, among those are wedding rings.
Tungsten as Wedding Rings
Part of the huge collection of tungsten jewelry usually includes wedding rings. This is because, apart from any other kinds of jewelry, wedding rings are the only objects susceptible to damages because of daily wear. Tungsten, being a very durable material used for heavy equipments, became the perfect material for making wedding rings as it conveys a message of permanence, a perfect reflection of the couple's relationship. Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum. Its hardness makes it ideal for rings that will resist scratching, are hypoallergenic, and will not need polishing, which is especially useful in designs with a brushed finish.
Another form of tungsten is also used as a main catalyst for tungsten jewelry, and that is tungsten carbide. The difference of tungsten carbide from tungsten is that its a lot tougher. Highly resistant to any kind of scratches, tungsten carbide is able to hold its shine for years, another perfect feature used in wedding rings.
