China has become a major exporter of extruded aluminum

Since the beginning of this year, the export situation of extruded aluminum extrusions in China has presented a pleasant scene. From January to April, the total net export volume of aluminum extrusions in China was 33.37 kt, which was almost the same as 34.005 kt in the same period of last year. With the development of global economic integration and the increasingly rational structure of China's aluminum extrusion industry, and the strengthening of market economy, as well as the increasing product quality, the international market competitiveness of aluminum profiles in China will increase year by year. Exports will increase year by year, and China is gradually becoming a major net exporter of aluminum profiles in the world. Although as early as 1956 when Northeast Light Alloy Co., Ltd. was established, China had a complete aluminum extrusion industry. In 1971, the Ministry of Foreign Trade of China introduced eight hydraulic aluminum extrusion presses from Ube Industries, Japan. But they are all extruded industrial profiles. China's architectural aluminum profile extrusion industry began in March 1980. The aluminum profile production line jointly constructed by the Guangzhou Second Light Industry Bureau Aluminum Products Industry Corporation and the Hong Kong China Aluminum Corporation was made in the Yuancun Aluminum Products Factory in the eastern suburbs of Guangzhou. Put into production, there is a 15MN hydraulic extruder imported from Xinjie Industry Co., Ltd. of Taiwan Province. The smelting furnace and the anodizing production line are designed and manufactured by themselves. However, the refrigerator of the anodizing production line was imported from Taiwan Province. In the initial stage of construction, ingots and molds were also purchased from Hong Kong. Therefore, the aluminum profiles produced at that time were sold back to Hong Kong as compensation trade. Subsequently, the Hong Kong Wanbao Aluminum Co., Ltd. and the Shenzhen Xilin Industrial Co., Ltd., a subsidiary of the Jilin Diesel Engine Plant, jointly built an aluminum profile plant built in Shenzhen in July 1980. Two hydraulic extrusion machines with 6 MN of Taiwan New Swimming Co. , A fuel burner. Initial production of small industrial profiles, and later production of building profiles. In 1980, Yingkou Aluminum Factory and Tianjin Aluminum Alloy Plant respectively imported a 16.3MN hydraulic press from the Japanese Ministry of Industry and Industry to produce aluminum profiles for the domestic construction industry. It can be seen that China's construction aluminum extrusion production started in the south and the north almost simultaneously. The mid 80s of the last century was the period of development of aluminum profiles in China. In 1986, there were 175 aluminum extrusion plants with a production capacity of 38kt/a and about 400 extruders. From 1989 to 1990, China's restrictions on the use of aluminum in construction led to a decline in the production of aluminum profiles. However, since 1991, China has again set off an upsurge in the construction of aluminum profiles. This climax was even greater than in the mid-1980s. The scope of spread is wider. In 1997, the aluminum extrusion industry reached its highest peak. According to the survey, at that time, there were extrusion factories in all provinces and cities except Tibet, and there were also 5 in Hainan Province. There were a total of 1142 in the country and more than 2800 extrusion machines were kept. More than 2350kt/a. Since then, China's architectural aluminum extrusion industry has completed a purely quantitative development period, and has entered a stage of higher-level quality, variety, benefit, and structural adjustment. After structural adjustment in recent years, the number of aluminum extrusion plants has dropped drastically to below 600. (Relevant departments are summarizing information on the issuance of production licenses for construction aluminum products, and can publish relevant materials in July), for example, in Hainan Province All 5 extrusion plants were closed. However, China's industrial aluminum extrusion industry is in a period of rapid development. After more than 20 years of development, some indicators of China's aluminum extrusion industry have dominated the world, such as the number of enterprises, the number of extrusion machines, and production capacity. In 2002, the output of extruded aluminum ranked second in the world, second only to the United States. Fortunately, China has become a major exporter of aluminum extrusion products, from the net exports of 35.981 kt in 1998 to 135.313 kt in net exports in 2002, with an average annual growth rate of 39.26%. What is more worth mentioning is that finished aluminum doors and windows and aluminum structural parts also increased at a relatively high rate, from 48.311kt in 1998 to 110.272kt in 2002, with an average annual growth rate of 22.92%. At present, in addition to increasing the export of aluminum profiles, manufacturers should pay special attention to exports of finished aluminum doors and windows and structural parts, because the economic benefits of exporting the latter are higher than those of the former, for example, the average export of 1t aluminum profiles in April 2002. The price is 2776.79 US dollars, while the export price of finished doors and windows and structural parts are 4230.30 US dollars / t, 4051.36 US dollars / t. The price of hollow aluminum profiles imported from China is 49.13% higher than that of export aluminum profiles. For example, in the first four months of 2003, imported solid profiles were 13.198 kt, the average price was 4141.11 US$/t, and 28.392 kt of such profiles were exported, with an average price of 2,776.79 US$/ t. The section of the imported hollow profile is more complex and the production is more difficult, but it is not that China cannot produce it. China has become a major producer, exporter, and exporter of aluminum profiles, but it must work hard to become a manufacturing powerhouse. China's consumption of aluminum profiles has entered a period of recession, while the future growth highlights the export volume of industrial aluminum profiles and expanded aluminum profiles. The main gaps between aluminum extrusion in China and industrialized countries are as follows: Excessive use of small enterprises, small extrusion machines, incompatibility of structural and market economy, weak technical development power, short die life, high energy consumption, and waste discharge Unsatisfactory and so on.
