3724 Ashwood Drive Essex, United States (PressExposure) April 17, 2009 -- Tungsten is one of the many materials used today to make wedding rings. Considered as one of the newly introduced catalyst for wedding rings especially for a man's wedding ring, tungsten wedding bands became as popular as platinum because of its sheer hardness and luxurious metal gray color. But other than tungsten wedding bands, what are the other applications of tungsten?
Tungsten, in metallurgy, has 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. Its high melting point also makes tungsten suitable for aerospace and high-temperature uses such as in electrical, heating, and welding applications, notably in the gas tungsten arc welding process.
Due to its conductive properties, as well as its relative chemical inertia, tungsten is also used in electrodes and in the emitter tips in electron-beam instruments that use field emission guns, such as electron microscopes. In electronics, tungsten is used as an interconnect material in integrated circuits, between the silicon dioxide dielectric material and the transistors. It is used in metallic films, which replace the wiring used in conventional electronics with a coat of tungsten (or molybdenum) on silicon.
Its density, which is 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. It is particularly useful in designs with a brushed finish. Though it can be as hard as gold and platinum, jewelry made from tungsten isn't as highly resistant resistant to scratches than that of platinum. What makes tungsten wedding bands in-demand is when carbon alloy is added to make a new material called tungsten carbide.
Wedding rings made of tungsten carbide are now tougher than tungsten alone. Carbon made it more highly resistant to scratches and gained a more lustrous look with its glossy black hue and mirror-like shine that would last for years. Tungsten carbide has also opened a new choice for men. Because of its features, tungsten wedding bands are perfect as men's wedding rings.
