It is a mixture of tungsten and carbon alloy which transforms the metal to one of the world's strongest bond, with a hardness rating of 8.5 and 9.5 on the Mohs hardness scale. Tungsten alone is a very hard and dense metal and has the highest melting point of all metals at 6100 degrees, but is still vulnerable to scratches and damages like other precious metals.
We use it in our wedding bands due to the fact it is four times harder than titanium, double the strength of steel, and virtually scratch proof, which customers love as the biggest complaint about rings and bracelets of lesser composition is that they are easily scratched.
As with any purchase you would make it is necessary to ask a jeweler which metal was used in making your wedding ring. Many tungsten ring manufacturers would use cobalt as a binding material to save money as it is a much cheaper manufacturing process.
The problem with using cobalt is that the cobalt will bond to oils in your skin and leeches out the wedding ring thereby causing the ring to oxidize. Oxidation of a wedding band looks like the tarnish of silver jewelry. At TitaniumKay we create our tungsten wedding rings only with nickel binder which makes them chemically inert, do not oxidize, and hypoallergenic. Many bricks and mortar jewelry stores will not know what the composition of the jewelry they are selling. If they do not know then more often than not the rings and bracelets will scratch and become worn over time.
Due to the extreme hardness of tungsten carbide, wedding bands created from this combination will not wear or become heavily scratched from daily wear. When you are ready to make your selection and buy your jewelry be sure to take extra pre-caution in determining proper size as these rings are not able to be sized unlike gold and silver. Another consideration is engraving on these rings will not show well unless laser machine is used in the process.
YES. Our tungsten carbide jewelry is hypopallergenic and safe to wear. It will not cause irritation reaction or rashes on any skin type.
