in recent years, with chinas massive infrastructure investment and the rapid advance of industrialization process, aluminum as building areas and important applications in the mechanical industry material, its rapid growth in output and consumption, the industry of our country has become the worlds largest aluminum production base and the consumer market. after nearly 10 years of rapid growth, chinas aluminum industry entered a new stage of development and showed a lot of new development trend.
the present situation of global and chinese aluminum industry around the world
global aluminum production and marketing situation. from the point of capacity distribution, can produce aluminium profile of the worlds 2009 countries and regions around 95, more than about 2200 production enterprises, the production capacity in china accounted for more than 50%, the proportion of world output can be ranked first.
with the global economic growth and aluminum use expanded, global consumption of aluminum by about 8.69 million t growth in 2001 to 2001 of the 15.5 million t, compound annual growth rate of about 7.5%. is expected in 2012, the global aluminum consumption will amount to about 16.69 million tons.
in regional terms, from 2001 to 2009 of the worlds major regional consumption present a different trend, consumption proportion rising rapidly in china, europe and north america took on a downward trend. by the end of 2009, chinas consumption share of global consumption ratio of 47%, while europe, north america and japan accounted for 21%, 8% and 21%, respectively, have been developed for aluminum consumption in our country.
from the point of application field, the construction industry is still the main field of aluminium profile application, far more than other areas of consumption, consumption increases year by year, by 2009 more than 63% of the total consumption. points region, north america, europe and other developed regions in 2009 aluminum consumption in the field of industrial average proportion is more than 50%, and aluminum consumption is only 32%, in the field of industry in our country in the field of industrial consumption ratio is relatively low.
aluminum industry present situation in our country. aluminum production in china increased from 2001 of 1.719 million t to 2009 t, 2009 compound growth rate of 19.8%. in 2009 our country building aluminum and industrial aluminum production is 4.96 million t and 2.33 million t respectively. aluminum production in china will be more than 10 million t, 2010, including building aluminum consumption is expected to exceed 6 million t, and by 2012 aluminum production in china is expected to reach about 14.4 million tons.
the main downstream industry development, its influence on the aluminum industry
in the field of construction and real estate. in recent years the rapid growth of domestic construction and real estate industry is one of the biggest aluminum consumption, accounts for about 68% of domestic aluminum consumption. in the field of the construction points and varieties of aluminum consumption, aluminium alloy door, window, curtain wall profiles and accounts for the main part.
《in 2009 chinas urban residential development report》 pointed out that at the end of 2005, chinas per capita housing area of 26.11 square meters. policy of housing and urban-rural development research center released the 2020 residents living in our country target prediction research report mentioned in the "2020 chinas urban per capita housing area is expected to 35 square meters". therefore, in a long time in the future, every year need a lot of new houses. according to the ministry of construction is expected, since the 2005-2005, china will add a: the gross area is approximately 30 billion square meters.
according to the 2011 ~ 2020 new construction area of 20 billion square meters calculation (measure according to the area account for 15% of the housing area, doors and windows when about 55% using aluminum alloy doors and windows material in our country, aluminum doors and windows need 8 kg per square metre building material), 2011-2020 new residential annual demand for aluminum construction profiles of 1.32 million tons.
update old building, the transformation of architectural aluminum demand, from the international experience, when a countrys per capita housing area is greater than 25 ~ 35 square meters, the countrys old buildings updates will come into a period of rapid growth. from now to 2020 in our country will be in the stage. to our country existing building area of 45 billion square meters, for example, every year, about 10% of 4.5 billion square meters of construction need to transform, is equivalent to about 675 million square meters of the doors and windows, calculated at 55% of the doors and windows material for aluminum alloy, each year about building aluminum about 2.97 million tons.
with large-scale construction of new rural areas and small towns, the construction of the aluminum industry scale effect, make construction aluminum prices gradually reduce, the good performance-to-price ratio makes architectural aluminum rural are widely used in our country. predicts 2015, the proportion of new rural areas and small towns of new construction area of new urban construction area will be considerable, of about 3.5 billion square meters, about 1 million t at least can bring architectural aluminum new market space.
in the industrial field. at present, chinas industrial aluminum extrusions total are only about 30%; compared with europe, north america and japan aluminum consumption structure, industrial consumption ratio reached 60%, 55% and 60%, respectively, are much higher than our country. differences in consumption structure reflects chinas aluminium in the field of industrial production, development and application, indicates chinas industrial aluminum consumption has great room for growth. in the next 5 ~ 10 years, chinas industrial aluminum consumption will continue to grow, the proportion of aluminum products will from the current 30% to about 2015, 45 ~ 50%, and according to our country government related planning, the next 10 years, industrial materials accounted for the proportion of aluminum are always to be close to 70%.
aluminum in industry is mainly used in transportation (including automobile manufacturing, rail transportation, equipment and machinery and equipment manufacturing, durable consumer goods industry (including light), respectively in the applications of aluminum in china accounted for about 10%, 10% and 12%. |
