3724 Ashwood Drive Essex, Florida (PressExposure) April 13, 2009 -- One of the most popular types of wedding rings today is the Tungsten wedding ring. Though this kind is new in the market, it has quickly become sought after and in-demand through out the world. Because of this, many people have started asking about tungsten rings. What is it made of? What makes it popular as a wedding ring? Are there any bad effects that come with wearing a tungsten wedding band?
First of all, tungsten is a steel-gray metal naturally found in several ores, including wolframite and scheelite. It has the highest melting point of all the non-alloyed metals and the second highest of all the elements after carbon. Because of its ability to retain its hardness at high temperatures and also because it has a high melting point, elemental tungsten is used in many high-temperature applications. These include the light bulb, the cathode-ray tube, and vacuum tube filaments, as well as heating elements and nozzles on rocket engines. Tungsten's high melting point also makes it suitable for aerospace and other uses including electrical, heating, and welding applications, notably in the gas tungsten arc welding process.
Because of its similarity in density to gold, tungsten is often used in jewelry as an alternative to gold or platinum. Its hardness makes rings resist scratching. It is also hypoallergenic and does not need polishing which makes it especially suited for designs with a brushed finish.
Aside from all these characteristics, another thing that makes the Tungsten wedding ring popular is its lustrous dark hue that is often buffed to a mirror finish. This color is more similar to that of hematite than to that of platinum. The finish, however, is highly resistant to scratches and scuffs, which is perfect for holding its mirror-like shine for years. The only reported bad effects caused by wearing a ring made out of tungsten happens when the ring is made by combining tungsten and cobalt. According to some reports, unwanted reactions may happen between the cobalt and the natural oils on human skin. Skin oils can cause the cobalt to leach from the material. In other cases, the reactions are said to cause possible irritation of the skin and permanent staining of the jewelry itself. This is why a lot of manufacturers now advertise their jewelries to be "cobalt free". This is achieved by replacing the cobalt with nickel as a binder.
