[China Aluminum Industry Network] Global electrolytic aluminum production has grown steadily and the power to increase production still comes from China. In 2005, the world output of electrolytic aluminum was 31.91 million tons, an increase of 6.45% year-on-year, of which China's output was 7.67 million tons, a year-on-year increase of 15.07%. In 2006, the global output of electrolytic aluminum reached 33.8 million tons. In June 2006, the global average daily output (excluding China) was 82,200 tons, which was an increase of 700 tons compared with the average daily output in May, which was a 0.09% increase from the previous period. In June, the domestic output of electrolytic aluminum was 780,300 tons, and the average daily output of electrolytic aluminum production was 26,000 tons, which was an increase of 1975 tons compared with the average daily output in May, which was an increase of 7.59%. China is still the main driving force behind the global increase in electrolytic aluminum production. Because China’s output accounts for a global share of 24.9%, the change in China’s output has played a decisive role in the global supply of electrolytic aluminum. The development status of China's electrolytic aluminum industry has determined that China's domestic electrolytic aluminum supply has been relatively abundant. In 2005, the average electrolytic aluminum production capacity was 10.7 million tons, and the capacity utilization rate was 75%. From the domestic data in June, China’s production capacity has been released to some extent. . China has built 11 electrolytic aluminum projects with a total capacity of 1.12 million tons. There are still 10 proposed electrolytic aluminum projects with a total capacity of 1.4 million tons. In 2006, electrolytic aluminum production capacity reached 11.6 million tons, and in 2007 it reached 12.5 million tons. The electrolytic aluminum construction process is simple. The technical content is low. The construction period is short and there are sufficient capital inputs. It takes only 9 months from start of construction to completion and production. The alumina production capacity of the electrolytic aluminum upstream industry rapidly expanded, and the industrial chain extended to the electrolytic aluminum industry, becoming the main driving force for the growth of electrolytic aluminum production capacity. The stage of growth and development of the electrolytic aluminum industry determines that production growth is the main tone, electrolytic aluminum companies compete, mergers and acquisitions, and continuous expansion, the increase in industry concentration, will also promote the growth of production capacity. The aluminum consumer, the purchaser of the electrolytic aluminum industry, is rapidly developing the economy in China. In the process of urbanization in China, consumer products such as infrastructure, public utilities, housing, and automobiles have greatly stimulated the demand for electrolytic aluminum in China. The electrolytic aluminum industry is in a period of high-speed development and the industry has survived the survival of the fittest and the industry has become more concentrated. From 2003 to 2005, the total output of electrolytic aluminum increased from 5.54 million tons to 7.67 million tons, and the output increased by 2.13 million tons, of which only China's top ten electrolytic aluminum plants achieved an increase of 910,000 tons. The number of manufacturers decreased from 141 to 95. The average production scale of individual manufacturers increased from 39,000 tons in 2003 to 80,000 tons in 2005.
