Tungsten Rings symbolize forever with their scratch resistant
hard metal surface. Tungsten rings have forever polished brilliant surface
finishes. ForeverMetals.com a tungsten carbide ring manufacture
retailer provides optimal comfort while wearing tungsten carbide ring
when putting it on or removing it. Forever Metals tungsten carbide
wedding bands are engineered to be maintenance free. A lifetime
warranty is accompanied with every jewelry purchase. ForeverMetals.com can
create a unique piece of jewelry with a style, polish and
texture that will last a lifetime. ForeverMetals.com offers
tungsten carbide rings with precious metal inlays of sterling
silver, rose gold, white gold and yellow gold. The tungsten
carbide portion of the ring will maintain its original polish
and luster for life, while the softer inlaid precious metals
will eventually develop a textured appearance over time,
creating an attractive contrast against the lasting polish of
the tungsten carbide.
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 900 -
2200°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 10 times
harder than 18k 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.
Not all tungsten rings are the same. Please be aware not all
ring manufactures use the same grade of tungsten. Some use a
lesser quality tungsten grade that is more susceptible to
scratches. Be sure to purchase from a reputable company.
There is no cobalt in our tungsten jewelry. All tungsten
jewelry from Forever Metals is tried and tested with sweat stain resistant
over 48 hours. All of our tungsten carbide rings are made with
the superior nickel binding powder and tungsten carbide
combination.
Nickel- powder are superior for several reasons. Nickel- powder tungsten carbide is hypoallergenic, chemically
inert and therefore will not oxidize, cause rashes, or irritate
the skin. We do not use cobalt as it can have an adverse reaction with
some wearers' skin, sometimes causing a rash. Cobalt bonds with oils in the skin and leeches out of the ring,
resulting in oxidation. The oxidation appears similar to
tarnished silver, but cannot be removed by polishing or
grinding.
Nickel, on the other hand, does not bond with oil and
therefore does not oxidize.
Tungsten rings are rich in color, lustrous shine, and
sleek new designs. Black tungsten is the hottest new look in
tungsten wedding bands and is proving to be a popular choice for
brides and grooms wanting wedding bands that express their
individuality.
Tungsten carbide is naturally grayish in color, 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 of
these wedding bands by extending their service life through high
wear resistance and low surface friction. We have tested black tungsten wedding bands for
many years now, and found
that they are resistant to typical wear and scratching.
