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.
- Aluminium keeps its toughness down to
very low temperatures, without becoming brittle like carbon
steels. It is easily worked and formed. Aluminium conducts
electricity and heat nearly as well as copper.
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.
