Why Tungsten Carbide is Used More than Other
Materials Often?
Tungsten Carbide is one of many inorganic
chemical compounds which contain equal of
tungsten and carbon atoms. Tungsten carbide in
its most basic form is a fine grey powder which
can be pressed and formed into shapes for use in
industrial machinery, abrasives, tools and
jewellery as well.

Fact Sheet of Tungsten Carbide
Tungsten Carbide is almost three times more
rigidity than steel with a Youngs modulus of
approximately 550 GPa, and is much denser than
steel or titanium. Its comparable with corundum
or sapphire in hardness and can only be polished
finished with abrasives of superior hardness
such as silicon carbide, cubic boron nitride and
diamond amongst others, in the form of powder,
wheels and compounds. Tungsten carbide is an
incredibly versatile material that comes in
numerous different types to give varying
properties. These varying characteristics are the
main reason for its popularity in a range of
applications and industries.

How Tungsten Carbide is Formed?
In typical conditions when uncombined, Tungsten
is a steel grey colored metal found naturally on
Earth when mixed with chemical compounds. Though
it was first discovered back in the year 1781,
the free element in Tungsten has gained a
reputation for its tough physical properties,
especially for its highest melting
point. Tungsten carbide is an inorganic compound
formed from equal parts of Tungsten and Carbon.
It is formed by reacting Carbon and Tungsten at
temperatures of between 1400 to 2000 degrees
Celsius. These high temperatures make it ideal to
be for mills and cutting tools for industrial
use, which are able to required heavy use and
high temperatures.

• Tungsten carbide starts off as a fine grey powder
  which is further used for an excellent abrasive
  because of its hard wearing properties. The
  powder form can be processed and formed into a
  desired shape such as tools, machinery and
  jewellery.
• The rare and extraordinary physical properties
  retained by Tungsten Carbide makes it useful for
  a variety of applications. It is enormously
  strong and wear resistant is so high that it can
  cut or scratch any scarce number of materials on
  earth.
• Tungsten carbide today is available in different
  grades and with varying properties which depends
  on its uses. There are several grades of carbide
  which vary on just a few parameters grain size,
  hardness, and the degree to which a binder is
  used.

How Much Strength Does Tungsten Carbide Offer?
Transverse Rupture Strength (TRS)

• The transverse rupture strength (TRS) of Tungsten
  Carbide with Cobalt variations is sometimes
  regarded as an indication of toughness which
  increases as hardness decreases. Upon using
  controlled group of tungsten carbide with cobalt
  samples with consistent TRS values, it
  demonstrates a different relationship between the
  TRS and hardness of Tungsten Carbide with Cobalt
  compounds.

• TRS is a measure of the strength of Tungsten
  Carbide. Tensile strength is not used on tungsten
  carbide because it is too brittle and accurate
  readings cannot be obtained. As a rule of thumb
  the tensile strength of tungsten carbide is
  approx half of the transverse rupture strength

Compressive Strength
Compressive strength is measured by compressing a
right cylinder test piece between two tungsten
carbide blocks held in line by an outer sleeve
assembly. The compressive strength of tungsten
carbide is higher than for virtually all metals
and alloys. This high compressive strength makes
it possible to compress carbon at one million PSI
from man-made diamonds.
Impact Strength
This measures the resistance of tungsten carbide
to shock loading by a drop weight impact test.
This is a more reliable indication of toughness
than TRS readings.

From the above mentioned points it is clear that
why people choose tungsten carbide over other
materials for various uses in industrial and
commercial space. Why you need tungsten carbide?
