2. About Metal Powders
Metal Powders are precisely engineered
materials that meet a wide range of
performance requirements. These
engineered materials offer wide latitude
to develop materials with properties
tailored to the application through metal
alloying. These engineering properties
are affected by several factors that
include material type, powder
fabrication process and the component
manufacturing process

3. Powder Metallurgy
Powder metallurgy is a highly developed
method of manufacturing reliable
ferrous and non-ferrous metal parts. The
process entails mixing powders and
compacting in a die to give shapes that
are then sintered or heated to bond
particles metallurgically. As more than
97% of the starting materials reach the
finished product, powder metallurgy is a
process that conserves both energy and
materials.

4. More about Metal Powders
Metal powder technology is one of
the most established production
methods nowadays in all kinds of
industries
Metals commonly used in powder
form include iron, steel tin, nickel,
copper, aluminum and titanium.
Refractory metals include tungsten,
molybdenum and tantalum.
Bronze, brass, stainless steel and
nickel cobalt alloys are also used.

5. Powder quality
Powder particles range from 0.1 to 1000 micron in
size and must be carefully controlled. Major
production methods include the atomization of
molten metals, reduction of oxides, electrolysis
and chemical reduction. Particle size distribution
is a critical parameter. Powders with narrow
particle size distributions behave predictably
during mixing and mould filling; perform better
during hot or cold compaction and sintering; will
give a uniform coating in spray applications; and
ultimately will give improved final product quality.

6. Technology
Metal powders are made either by
gas atomization , or grinding , and
are then classified using dynamic
classifiers or cyclones to obtain the
precise particle size distribution. To
form the final end-user product,
the metal powders are then used in
various consolidation processes
such as extrusion, injection
molding, blending, compaction,
sintering.

7. Metal Powder applications
Metal powders are used in a wide
variety of applications which
include dietary supplements in
food processing, additives in paint
and other coatings, as pigments in
printing and packaging, in solid
fuels and cements. Probably the
major area though is in the cost-
effective production of metal
components for a vast array of end
uses.

8. Market
The global market for metal
powder witnessed rapid
growth in 2013, and is
projected to grow at a CAGR
of 3.80% during the forecast
period, that is, from 2015 to
2020, to reach USD 4,062.2
Million by 2020.
