Characteristics Of Aluminium
-
Aluminium is the third most abundant element in
the Earth's crust. In nature however it only exists
in very stable combinations with other materials
(particularly as silicates and oxides) and it was
not until 1808 that its existence was first established. 
-
Aluminum is light. Its density is only one third
that of steel. Aluminum is resistant to weather,
common atmospheric gases and a wide range of liquids.
Aluminum has a high reflectivity, and therefore finds
more decorative uses. Aluminum has high elasticity,
which is an advantage in structures under shock loads.
Supply and Demand :
Global Scenario
- Aluminium ore, most commonly bauxite, is plentiful
and occurs mainly in tropical and sub-tropical areas
- Africa, West Indies, South America and Australia.
There are also some deposits in Europe
- The leading producing countries include the United
States, Russia, Canada, the European Union, China,
Australia, Brazil, Norway, South Africa, Venezuela,
the Gulf States (Bahrain and United Arab Emirates),
India and New Zealand; together they represent more
than 90 percent of the world primary aluminium production.
- The largest aluminium markets are North America,
Europe and East Asia.
- The global production of aluminium is about 27.7
and 28.9 million tons in 2003 and 2004 respectively.
- China, Russia, Canada and United States produced
about 6.1, 3.6, 2.64 and 2.5 million tons of aluminium
in year 2004 respectively.
Indian Scenario
- India is considered the fifth largest producer
of aluminium in the world.
- It is estimated at about 3037 million tonnes for
all categories of bauxite (proved, probable and possible).
With the present level of consumption of aluminum,
the identified reserves would have an estimated life
of over 350 years. India's reserves are estimated
to be 7.5 per cent of the total deposits and installed
capacity is about 3 per cent of the world.
- In terms of demand and supply, the situation is
not only self-sufficient, but it also has export
potential on a competitive basis. India's annual
export of aluminium is about 82,000 tonnes.
- India’s annual consumption of Aluminum is
around 6.18 lakh tons and is projected to increase
to 7.8 lakh tones by 2007.
- About a decade back, the primary Indian aluminium
producers were BALCO, NALCO, INDAL, HINDALCO and
MALCO. Of the five, two (BALCO and NALCO) were in
the public sector while the other three were in the
private sector
- As a result of the process of liberalization of
trade in aluminium, India has emerged as a net exporter
of aluminium, on competitive terms. Government monopoly,
in terms of aluminium production, removal of price
and distribution control over aluminium, has been
diluted in favour of private sector. The ownership
pattern in private sector has undergone changes.
With the takeover of INDAL by the HINDALCO, it has
emerged as the major producer of aluminium in the
country.
World Aluminium Markets
- LME, TOCOM, SHFE and NYMEX are the important international
markets that provide direction to the aluminium prices.
