Tungsten Carbide
Ring Manufacturing
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 **0 - ***0°C 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 *0 times harder than *8k gold and four times harder than titanium and is equal to a natural sapphire's hardness. In addition to its design and high polish, part of its attraction to consumers is its technical nature.
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.
Tungsten jewelry is very hard and in comparison, titanium, a very hard metal, is about 6.5 on Moh's scale. Gold, silver, and platinum range from 2 to 4 on the scale. Sand ranks up there at 7 and your teeth, depending on your diet, range right around 4. The Mohs scale is more or less a "scratch test" so you can see why Tungsten is such a durable ring. Have some fun with them by trying to scratch them with a metal file. Titanium ring manufacturing companies routinely cut out their titanium rings using tungsten carbide cutting tools. There are just no rings that can compete with tungsten's durability.
Tungsten does not gain its extreme hardness until it is combined with a carbon alloy, transferring it into tungsten carbide (WC). 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 durable enough for every day use. You are no longer required to constantly remove and replace your ring to protect its finish.
