Tungsten Rings and Wedding Band Jewelry

Tungsten Rings symbolize ‘forever’ due to their scratch resistant, hard metal surface. Tungsten rings also exhibit the ‘forever’ brilliance of its finishes. Forever Metals, a tungsten carbide ring manufacturer / retailer, only provides comfort-fit rings. As the name suggests, these rings far exceed the comfort level of the traditional straight fit ring. The straight fit ring is difficult to wear and remove and often has a tendency to injure the finger during certain activities. Forever Metals tungsten carbide wedding bands are nearly maintenance free. A lifetime warranty is accompanied with every jewelry purchase. Forever Metals can create a unique piece of jewelry with a style, shine and texture that will last a lifetime. Tungsten carbide rings our offered with precious metal inlays. The inlays may consist of sterling silver, rose gold, white gold and yellow gold. The major composition of the ring is tungsten carbide which will retain its luster for ‘forever’, while the softer inlaid precious metals may acquire a textured appearance over time, creating an attractive contrast against the brilliance of the tungsten carbide background.

Tungsten Carbide Ring Manufacturing.

Tungsten rings are composed of a metal alloy of tungsten carbide and nickel. The alloy allows for maximum hardness and rigidity without sacrificing tensile strength. Each tungsten carbide ring is cut and polished with diamond tools. Since the alloy is so hard, Tungsten rings are not sizable by ordinary jewelers' tools. Tungsten metal powder is converted to tungsten carbide (WC) by reacting it with pure carbon powder, e.g. carbon black, at 900 - 2200°C in pusher or batch furnaces, a process called carburization.



Tungsten is an extremely hard and dense element. Combined with carbon and other elements, it becomes tungsten carbide, and 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 equal to a natural sapphire's hardness.



Tungsten carbide’s hardness assures long lasting beauty. Permanently polished tungsten rings exhibit a brilliant high polish and resist scratching longer than any material offered for public sale. Tungsten rings will not bend under normal wear or rugged activity. Only under extraordinarily harsh conditions can the ring be affected.



Tungsten jewelry is very hard and in comparison, titanium, also a very hard metal, is 6.5 on Moh's scale. Gold, silver, and platinum range from 2 to 4 on the scale. Compare these numbers against Tungsten carbide’s 9.0 and you will understand why this material can justify the claims that the rings are extremely durable and virtually indestructible. Titanium ring manufacturing companies routinely cut out their titanium rings using special tungsten carbide cutting tools.



As described above, tungsten carbide is virtually indestructible, and has been widely used for decades in industrial applications such as cutting tools, mining machinery, and rocket engine nozzles. The unique formula of our tungsten carbide allows Forever Metals’ rings to be both visually stunning and rugged enough for every day wear even withstanding the harshest of activities.



Not all tungsten rings are the same. Be aware that not all of the ring manufactures use the same tungsten alloy. Some use a lesser quality tungsten grade that is more susceptible to scratches. There is no cobalt in our tungsten jewelry. All of our tungsten carbide rings are made with nickel powder and tungsten carbide to form the most superior tungsten combination.



Nickel powder is superior for several reasons. Nickel powder/tungsten carbide is hypoallergenic, chemically inert and therefore will not oxidize nor irritate the skin. Forever metals does not use cobalt as it can have adverse reaction with the user’s skin, sometimes causing a rash. Additionally, cobalt bonds with oils in the skin, leeching materials out of the ring, resulting in oxidation. The oxidation appears similar to tarnished silver, and restoration is difficult unless the substance is removed with extensive polishing or grinding. Nickel, on the other hand, does not bond with oil and therefore does not oxidize.



Tungsten rings are rich in color and provide a lustrous shine and sleek design. Black tungsten is the hottest new look in tungsten wedding bands and is a popular choice for brides and grooms wanting wedding bands that express their individuality.



Tungsten carbide is naturally grayish, and because of its extreme hardness is a perfect base metal for physical vapor deposition (PVD) coatings IP (ions plating). Under carefully controlled manufacturing conditions, and using this special process, the exterior surface color of naturally gray tungsten carbide wedding bands can be permanently changed to a rich and luxurious black diamond (C10) coating. The interior is also coated except for a very thin line used for metal identification. The IP coating on our black tungsten wedding bands not only produces a handsome wedding band that is similar to the color of onyx, but it improves the material properties by extending their service life because of its high wear resistance and low surface friction.
