Facts about Tungsten Carbide Jewelry

Tungsten Carbide jewelry for engagement and wedding rings are ideal when durability is the main consideration. Carl Wilhelm Scheele is credited with the discovery of Tungsten in 1781, but it took nearly two centuries for applications to be developed to fully utilize the attributes of this metal.

Today in 2013, there are jewelers who now market “pure” tungsten wedding bands. But in this case the purity of the metal is not in the best interest of the wearer. Tungsten used alone, results in jewelry that is easily scratched, destroying the beauty of the ring.

On its own, the unique hardness of Tungsten is legend, but to bring out its full potential it must be combined with a carbon alloy, transforming it into Tungsten Carbide,measuring between 8.5 and 9.5 on the Mohs hardness scale: only diamonds which measure 10 on the Mohs scale are harder. Innovative jewelers such as Titanium Kay were among the first online merchants to recognize the high level of customer satisfaction that Tungsten Carbide wedding bands would produce.

Using Tungsten Carbide for jewelry craft is the newest application to take advantage of its qualities, but it is hardly a new metal. Hundreds of industrial applications such as space craft, deep terrain mining and cutting tools use Tungsten Carbide because it's twice as hard as steel and four times harder than titanium.

It is the alloy metal, in most cases nickel-binder carbide which gives Tungsten Carbide its “permanently polished” appearance. There are tungsten rings that are created using cobalt as a binder because it's cheaper. However the problem with using cobalt is that it bonds with oils in the skin, over time, the cobalt leeches out of the ring and can irritate the skin because of oxidation. Unfortunately once this happens no amount of grinding or polishing will remove the oxidation which is very similar in appearance to tarnished silver.
