About tungsten carbide bracelets and pendants
Discover the amazing look and durability of tungsten carbide bracelets
and pendants. In an extraordinary process, Tungsten and Carbide powders
are forged together at 2,400 degrees Fahrenheit to form bracelets and
pendants that are virtually indestructible and scratch proof. Then they
are polished with a diamond compound, resulting in a polish and shine
that will last forever. Tungsten carbide is the perfect combination of
unbelievable strength with style and comfort.
Why Tungsten Carbide?
Tungsten is the only rare and exotic metal that can be permanently polished.
With gold, platinum and even tungsten bracelets and pendants , you will
notice varying degrees of scratching, denting and surface mars. However,
with tungsten carbide bracelets and pendants, the surface will maintain
it’s original beautiful shiny finish.
Many people also enjoy the heavy weight of a tungsten carbide bracelet
or pendant.
Hard Facts About Tungsten Carbide jewelry:
Tungsten Carbide makes the most wear resistant bracelets and pendants
available on the planet.
Tungsten is about 10 times harder than 18K Gold, 5 times harder than tool
steel, and 4 times harder than titanium. * Tungsten measures between 8
and 9 on the Mohs hardness scale. (Diamonds are a 10 - the highest.)
Our Tungsten bracelets and pendants are cobalt free.
The Manufacturing Process
Tungsten with carbon are ground into a powder and then compressed with
high pressure dies to form a bracelet link or pendant blank.
The blank is then placed in an oxygen free furnace at an astounding 6,200
degrees fahrenheit. This process called sintering creates the hardest
metal used bracelet/pendant making jewelry.
The piece is then cut and shaped using diamond tools with approximately
30 steps required for completion. The cutting and shaping of tungsten
carbide jewelry is similar in many ways to cutting and polishing of a
rough diamond.
The piece is then skillfully polished with diamond polishing tools and
wheels creating a permanent luster and polish not possible with other
metals.
Tungsten Carbide bracelets and pendants will remain polished forever.
It is a unique metal that epitomizes today’s man more than any other.
What’s the difference between Tungsten jewelry and Tungsten Carbide jewelry?
Some of our competitors sell Tungsten bracelets and pendants that do not
include Carbide. (Some of the retailers still call them Tungsten Carbide
however, so be careful.) A Tungsten only piece is basically only steel.
It is hard, but NOT scratch proof.
A Tungsten Carbide bracelet can only be scratched by a diamond or a product
containing the mineral corundum. If you see a Tungsten piece that has
carved details this bracelet/pendant does not have Carbide - it is a tungsten
only piece. Therefore, it will scratch.
Should I be concerned with Cobalt in my jewelry?
YES, absolutely !
Many Tungsten and Tungsten Carbide bracelets and pendants have Cobalt
in them. The alloy containing Cobalt is easier to procure and bracelets
and pendants containing Cobalt are being commonly sold. However, bracelets
and pendants containing Cobalt will develop a negative react to your skin.
After a short time period the ring will develop oxidation spots that cannot
be removed or polished out. This is due to the Cobalt reacting to the
human body. You can easily prevent this from happening by purchasing one
of our Cobalt free Tungsten Carbide bracelets and pendants.

History
(Swedish, tung sten: heavy stone) In 1779 Peter Woulfe examined the mineral now known as wolframite and concluded it must contain a new substance. Scheele, in 1781, found that a new acid could be made from tungsten (a name first applied about 1758 to a mineral now known as scheelite). Scheele and Berman suggested the possibility of obtaining a new metal by reducing this acid. The de Elhuyar brothers found acid in wolframite in 1783 that was identical to the acid of tungsten (tungstic acid) of Scheele, and in that year they succeeded in obtaining the element by reduction of this acid with charcoal. Tungsten occurs in wolframite, scheelite, huebnertie, and ferberite. Important deposits of tungsten occur in California, Colorado, South Korea, Bolivia, Russia, and Portugal. China is reported to have about 75% of the world’s tungsten resources. Natural tungsten contains five stable isotopes. Twenty one other unstable isotopes are recognized. The metal is obtained commercially be reducing tungsten oxide with hydrogen or carbon.
Properties
Pure tungsten is a steel-gray to tin-white metal. Very pure tungsten can be cut with a hacksaw, forged, spun, drawn, and extruded. The impure metal is brittle and can be worked only with difficulty. Tungsten has the highest melting point of all metals, and at temperatures over 1650oC has the highest tensile strength. The metal oxidizes in air and must be protected at elevated temperatures. It has excellent corrosion resistance and is attacked only slightly by most mineral acids. The thermal expansion is about the same as borosilicate glass, which makes the metal useful for glass-to-metal seals.
Uses
Tungsten and its alloys are used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work; for electrical contact points for automobile distributors; X-ray targets; windings and heating elements for electrical furnaces; and for numerous spacecraft and high-temperature applications. High-speed tool steels, Hastelloy(R), Stellite(R), and many other alloys contain tungsten. Tungsten carbide is of great importance to the metal-working, mining, and petroleum industries. Calcium and magnesium tungstates are widely used in fluorescent lighting; other salts of tungsten are used in the chemical and tanning industries. Tungsten disulfide is a dry, high-temperature lubricant, stable to 500C. Tungsten bronzes and other tungsten compounds are used in paints. Tungsten powder (99.9%) costs about $50/lb.

History
(Latin. carbo: charcoal) Carbon, an element of prehistoric discovery, is very widely distributed in nature. It is found in abundance in the sun, stars, comets, and atmospheres of most planets. Carbon in the form of microscopic diamonds is found in some meteorites.
Natural diamonds are found in kimberlite of ancient volcanic "pipes," found in South Africa, Arkansas, and elsewhere. Diamonds are now also being recovered from the ocean floor off the Cape of Good Hope. About 30% of all industrial diamonds used in the U.S. are now made synthetically.
The energy of the sun and stars can be attributed at least in part to the well-knowncarbon-nitrogen cycle. Forms
Carbon is found free in nature in three allotropic forms: graphite, diamond, and fullerines. A fourth form, known as "white" carbon, is now thought to exist. Ceraphite is one of the softest known materials while diamond is one of the hardest.
Graphite exists in two forms: alpha and beta. These have identical physical properties, except for their crystal structure. Naturally occurring graphites are reported to contain as much as 30% of the rhombohedral (beta) form, whereas synthetic materials contain only the alpha form. The hexagonal alpha type can be converted to the beta by mechanical treatment, and the beta form reverts to the alpha on heating it above 1000oC.
In 1969 a new allotropic form of carbon was produced during the sublimation of pyrolytic graphite at low pressures. Under free-vaporization conditions above ~2550oK, "white" carbon forms as small transparent crystals on the edges of the planes of graphite. The interplanar spacings of "white" carbon are identical to those of carbon form noted in the graphite gneiss from the Ries (meteroritic) Crater of Germany. "White" carbon is a transparentbirefringent material. Little information is presently available about this allotrope.
