“The problem with cobalt is that it bonds with oils in the skin and leeches out of the ring resulting in oxidation. The oxidation appears similar to tarnished sliver, but cannot be removed by polishing or grinding. The better choice is nickel-binder tungsten carbide which is chemically inert, will not oxidize and because it is hypoallergenic, there is no danger of irritation to the skin. Be careful about dealing with a jeweler that doesn’t specify that their tungsten wedding bands are made with the nickel binder alloy. Many jewelry stores do not know which alloy they are selling, and if they don’t know, it is most likely cobalt alloy or pure tungsten, which lacks the hardness of tungsten carbide and are easily scratched” says C.N. Millar of cptph.com.
He added that, “Tungsten carbide rings and tungsten carbide wedding bands are virtually indestructible. Both metals have been used extensively under the most grueling industrial conditions since the Machine Age began over 200 years ago, and have been proven to be among the most durable materials on the planet. Tungsten-carbide wedding rings are not only uncommonly beautiful, but take the concept of the tungsten ring even further. Carbide compounds are the stuff of heavy-duty cutting machinery and have military applications as well.”
Speaking on the move, Mr. C.N. Millar said, “Because of tungsten carbide’s extreme hardness, wedding bands made from this metal cannot be sized like gold, silver or platinum rings. When you are ready to purchase, make sure that you take extra care in determining the proper size. We recommend that you use a standard narrow ring gauge to accommodate for our comfort fit. We often find that people who guess their ring sizes or base them off of normal jewelry find themselves ordering a ring that is usually one half size too large.”
He concluded that, “On its own, tungsten is a very hard and dense metal, with the highest melting point of all metals – 6,100 degrees Fahrenheit. Alone, tungsten is vulnerable to scratches and damage just like any other metal, it gains its extreme hardness by being combined with a carbon alloy, transforming it into tungsten carbide, with a hardness between 8.5 and 9.5 on the Mohs hardness scale.”
