Project at a Glance
- Aluminum powder (uncoated) is also known
as aluminum powder, aluminum, aluminum flake, aluminum metal, metana.
- Aluminum powder is a light, silvery-white
to gray, odourless powder. It is a reactive flammable material.
- Aluminum powder is a fine granular powder
made from Aluminium. In form of powders, Aluminium is used for several
applications such as manufacture of slurry, explosive and detonators,
thermit process used for manufacture of ferro alloys and for specialised
welding applications such as rails, pyrotechnic to manufacture crackers,
sparkles and other pyrotechnic products; manufacture of aluminium paste,
paints and several powder components used in automobiles.
- The most important property of aluminium
powder to undergo a vigorous exothermic reaction when it gets oxidised finds
application in pyrotechnic process. In foundry, aluminium powder is used as
a deoxidant and exothermic tapping compounds to increase the yield of
casting.
- The aluminium powder is manufactured in
several forms such as flake-like particles, granular powder (atomised
aluminium) etc. For the production of aluminium powder, there are several
processes, one can use any of them.
- Aluminium powder is used as a blasting
agent and rocket fuel, as alkyl catalysts in the production of biodegradable
detergents, as a precursor for aluminium chlorhydroxide and aluminium
glycinate which are constituents of deodorants and anti-perspirants, as
fillers for epoxies and as pigments in paints and inks. Approximately 1,200
tonnes was used in 2000 in metallurgical applications, which accounts for
2-3% of aluminium powder shipments in the U.S.A.
- Aluminum powders are used in paints,
pigments, protective coatings, printing inks, rocket fuel, explosives,
abrasives and ceramics; production of inorganic and organic aluminum
chemicals; and as catalysts. Pyro powder is mixed with carbon and used in
the manufacture of fireworks. The coarse powder is used in aluminothermics (thermite
reaction).
- The aluminium powder is a consumable
product. Presently there are four major organised manufacturers of aluminium
powder. They are Metal Powder Company, Thirumangalam, INDAL, Mumbai, Khosla
Metal Powder Company, Pune and Arasan Aluminium Industries, Sivakasi. In
addition, there are a number of small scale industries located in Karnataka,
M.P., Maharashtra, Gujarat and Delhi with an installed capacity of 1 tonne
per day.
- In a recent report of DSIR, the total
production of aluminium powder in the country has been estimated at more
than 10,000 MT per year. DGTD has estimated the growth of demand between 8
to 10% per annum.
- The aluminium powder industry is of a
remarkable size. There is a growing market for export of aluminium powder
and paste. Good opportunities exist in the field of setting up new units in
small scale sectors with proven technology and appropriate quality
orientation.
- Today, BAI is one of just a handful of
companies in the world producing atomized aluminum powder.The plant capacity
is about 25,000 tons per year, an increase of 316% over 25 years with a
total investment of more than US $ 50 million
- During the last two years, India exported
aluminium powder worth USD 91,317,727 with total quantity of 61,400,229.
United States is the largest buyer of aluminium powder accounting for
exports worth USD 19,646,061 followed by Belgium and Mexico which imported
aluminium powder worth USD 14,996,955 and USD 6,792,095 respectively.
