3724 Ashwood Drive Essex, Florida (PressExposure) April 15, 2009 -- What makes a Tungsten wedding ring so popular with marrying couples? Before it was used in jewelry, tungsten's principal use involves high temperature purposes such as in light bulbs, cathode-ray tubes, or nozzles of jet or rocket engines. Because of its hardness, tungsten is also used to create heavy metal alloys such as high speed steels (containing 18% tungsten) used for cutting and drilling. Tungsten became popular as jewelry not only because of its hardness but also because of its properties that made it hypoallergenic.
Tungsten Wedding Ring into Tungsten Carbide Wedding Ring
Tungsten alone can be used to create jewelry such as tungsten wedding rings. Its toughness is ideal for everyday wear and tear. However, several disadvantages have been cited with tungsten when it comes to jewelry. Tungsten is still vulnerable to scratches from other forms of metals or anything it comes in contact with even though it is hard. Because of this and the demand for Tungsten wedding ring to be a bit more sophisticated, jewelers have found another catalyst to make tungsten more luxurious and tougher than before.
Tungsten carbide, a mixture of tungsten and carbon alloy, is a form of metal used in many applications particularly in machine tools. Tungsten carbide are often used for cutting through heavy and hard materials such as carbon steel or stainless steel, as well as in situations where other tools would wear away, such as high-quantity production runs. Tungsten carbide are also used for military purposes such as armor-piercing ammunition specifically used for heavy armored tanks.
The use of carbon alloy in a Tungsten wedding ring also made it a lot tougher as well as obtaining a more luxurious look than ordinary tungsten. Because of its lustrous black hue, tungsten carbide wedding rings became perfect as a man's wedding ring. Because of carbon, tungsten wedding rings became highly resistant to any scratches (although the use of abrasive materials such as diamond can still scratch it) and can hold its mirror-like shine for years. Although it offered more benefits than tungsten alone, jewelry made from tungsten carbide still posed some disadvantages especially the ones made with cobalt binders.
Tungsten Carbide Wedding Rings Causing Skin Irritation
Many manufacturers of this emerging jewelry material state that the use of a cobalt binder may cause unwanted reactions between the cobalt and the natural oils on human skin. Skin oils cause the cobalt to leach from the material. This is said to cause possible irritation of the skin and permanent staining of the jewelry itself. Many manufacturers now advertise that their jewelry is "cobalt free". This is achieved by replacing the cobalt with nickel as a binder.
