Tungsten Mens Rings Are Formal and Classy

By Mischa Leonne

People choose to wear tungsten rings for their strength, durability and long lasting finish. Tungsten rings are luxurious, dependable and classy. They are also virtually maintenance free due to their extreme hardness and long lasting polish. Tungsten carbide rings easily outlast silver, gold and even titanium jewelry, keeping their spotless shine for a lifetime.

However, there are many different ways that tungsten can be processed and turned into jewelry. Buyers of tungsten carbide rings - whether a men\'s tungsten carbide rings intended to hold up to tough use, or custom tungsten carbide wedding sets intended to last a lifetime - need to be aware of the different formulations that some jewelry manufacturers use. Some formulations do not offer the durability most tungsten ring buyers want!

Tungsten rings are composed of a metal alloy, tungsten carbide. The alloy allows for maximum hardness and rigidity without sacrificing tensile strength. Each tungsten carbide ring is cut and polished with diamond tools. Tungsten rings are not sizable by ordinary jewelers\' tools, the metal is to hard. Most tungsten metal powder is converted to tungsten carbide (WC) by reaction with pure carbon powder, e.g. carbon black, at 900 - 2200C in pusher or batch furnaces, a process called carburization. Tungsten is extremely hard and dense. Combined with carbon and other elements, it becomes tungsten carbide, which registers between 8.9 - 9.1 on the Mohs hardness scale. It\'s roughly 10 times harder than 18k gold and four times harder than titanium and is equal to a natural sapphires hardness. In addition to its design and high polish, part of its attraction to consumers is its technical nature. It gleams a kind of luster that borders on the originality, making person be addicted to it, dulcify.

Tungsten carbide hardness has an assuring long lasting beauty. Permanently polished tungsten rings take a brilliant high polish and resist scratching longer than any metal ever offered to the public. Tungsten rings will never bend out of shape.

Myth: Tungsten carbide rings should not contain nickel. Fact: In truth, tungsten carbide wedding rings are not made from pure tungsten. Pure tungsten in its natural form is an ore, and does not polish up to the shine that people love about tungsten carbide rings. Makers of tungsten carbide rings need to combine tungsten ore in a powder form with various binders and sinter it all together at very high temperatures in order to achieve the desired result - a beautiful, polished and nearly indestructible tungsten carbide ring. A nickel binder is the preferred formulation for tungsten carbide rings, as many other binders can cause your ring to discolor with wear. Many inexpensive rings use one of these lesser binders, and aren't pleasant to wear or look at!
