Know How Many Grades of Tungsten Carbide
Available in this 21st Century for Industrial
Usages the Strength They Provides?
Today, use of tungsten carbide has a record
setting growth in a number of different
applications throughout many industries. It has
now been used in a variety of products because
tungsten carbide is an incredibly versatile and
useful material possessing some of the unique
properties. There are over a dozen different
grades of tungsten carbide available to buy. When
evaluating or finding equivalents of tungsten
carbide grades, the important criteria here is to
specify two of three factors binder content,
hardness and grain size. When choosing between
the numerous distinct grades, it is important to
understand what properties are required for the
application. For example, grade CD-630 is
extremely hard wearing but only able to cope with
low impact, so it has perfect blades and seal
rings. On the other hand, CD-70 is designed to
endure high impact environments and is therefore
perfect for manufacturing harder dies.

Use of Tungsten Carbide

• Different tungsten carbide grades have different
  properties to showcase. All specifications are
  designed and engineered for a purpose and rigid
  controls are kept throughout production processes
  to ensure adherence to grade engineering. Quality
  control properties such as hardness, density and
  minimum transverse rupture strength were
  determined from tests made on each batch of
  powder before it is used in the manufacturing
  process.
• Other properties such as Youngs modulus of
  elasticity, Poissons ratio, coefficient of
  thermal expansion, thermal conductivity and
  electrical conductivity are used by engineers for
  design calculations. Properties such as
  comprehensive strength, gain size and abrasion
  resistance give the designer additional
  information about the suitability of the grade
  for the part being designed.

How Much Does Tungsten Car Strength bide Provide?
Minimum Transverse Rupture Strength (TRS)
The transverse rupture strength of tungsten
carbide is sometimes regarded as an indication of
toughness which increases as hardness decreases.
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.
Transverse rupture strength values are determined
by the amount of force needed to break standard
test pieces under the same test conditions.

Comprehensive Strength
Comprehensive strength is measured by compressing
a right cylinder test piece between two tungsten
carbide blocks held in line by an outer sleeve
assembly. The comprehensive 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. Tungsten carbide
permutations have a unique variety of properties,
high compressive strength, hardness and
resistance to wear, as well as a capability to
endure shock and impact. Typical applications are
seal rings, valves, linear bearings and blades.
Traditional tungsten carbides with cobalt binder
have limited corrosion resistance, making them
unsuitable for applications in which the wear
parts are functioning under both severe abrasive
and corrosive conditions.
