According to the direction of aluminum profile production, China's distinction between the categories of aluminum profiles is mainly industrial aluminum profiles and construction industry aluminum profiles. According to China's government departments on the development of aluminum profile production enterprise planning, in the next ten years, China's total production of aluminum profiles to further increase, so as to improve China's aluminum profile high-end products in the international market share. Therefore, China's aluminum profile production enterprises will have to improve their own production efficiency, improve the aluminum profile production and processing enterprises in the international market share of products for the development of China's aluminum profile industry.
1. Industrial aluminum profiles market development status.
(1) Overview of aluminum profiles. Aluminum element is one of the most abundant elements in all the metal element resources of the earth, and its use is quite extensive. Automobile manufacturing, shipbuilding, aviation, construction work production can not be separated from aluminum profiles, it is because aluminum material has very unique characteristics, making aluminum profiles in various industries is very widely used. At this stage, the speed of development of China's industry has accelerated, and the demand for aluminum profiles is also increasing, in order to meet the speed of development of the industry, it is necessary to improve the effciency of the production of aluminum profiles. The rapid development of China's industry has laid a good foundation for the wide application of aluminum profiles and the degree of demand, and at the same time, many excellent aluminum profile production enterprises have emerged, driving the rapid progress of the whole industry chain of aluminum profiles.
Take the construction industry as an example, with China's urbanization process continues to accelerate, the real estate industry is booming, has become the main source of China's national economic growth, and the development of the real estate industry, will inevitably lead to the development of the building materials industry, so the production of aluminum profiles and processing industry has become one of the most widely used materials in the building materials. Secondly, in many of the demolition of urban villages, the transformation of old neighborhoods in the project, but also for the production and processing of aluminum profiles provide a very broad consumer space. In short, with China's government departments on aluminum production and processing policy to promote the development of China's aluminum industry will be more rapid, for China's construction and industrial industry to provide strong support for the long-term development of the industry.
At this stage, it is the period of rapid growth of China's aluminum extrusion production and processing enterprises, China and the world's demand for aluminum extrusion is also further increased, the emergence of aluminum extrusion is the innovation and development of China's various industries to provide a very good material. For example, aluminum doors and windows in the construction industry, aluminum body in automobile production and manufacturing, these are one of the most advanced production materials, which is very important to promote the development of China's economy.
(2) The development status of industrial aluminum profile production. In the domestic aerospace, electronic and electrial appliances, containers and other industries under the rapid development of China's aluminum profile production and processing enterprises has been a significant development, aluminum profile production enterprises annual output has climbed year after year. Therefore, many of the aluminum profile production enterprises to increase the investment in aluminum profile production, in order to meet the real estate, aerospace, electronics and electrial appliances, container and other industries in the demand for aluminum profiles, China's aluminum profile production type gradually to the industrial profile and change, in order to promote the rapid development of these industries.
From a foreign point of view, the United States, Japan, Britain and other countries for rail transit aluminum profile demand compared to China accounted for a relatively high, but China in the field of construction aluminum profiles has been greatly ahead of these countries, so in order to keep up with the world trend of aluminum production, China must increase the production of aluminum profiles in the application of rail transit. At this stage, due to the lack of mastery of aluminum profile production technology, China's production of low and medium-end aluminum profile products have appeared overcapacity problems, while some high-end aluminum profile production technology is more short of. Therefore, China needs to import a large number of high-end aluminum products from abroad every year. In the face of the current fierce trade competition, which is extremely unfavorable for the development of China's aluminum profiles, so our country to improve the technical research and development of high-end aluminum profile products.
2.The main application analysis of industrial aluminum profiles.
(1) Containers industry development status and impact. According to statistics, China-made containers accounted for more than 95% of the total global container volume, China has been eighteen consecutive years of container production and sales of the world's first position in the country. The end of 2016, shipping prices were affected by the bankruptcy of HANJIN shipping and other factors, rose; since 2017, the volume of international trade has continued to recover, the containerized transport industry shows a gradual trend out of the downward cycle of adjustments, but this year's China-US trade frictions, and give the container transportation industry a head start, can not see the upward trend in the short term. At the same time, container transportation in China's domestic trade in transportation, although the start is relatively late, but the development is very rapid, the current domestic trade container throughput accounted for about 10% of the total container throughput of the main domestic ports, with the domestic shippers on the quality of logistics and transportation, efficiency and price requirements are increasingly improved, the domestic container transportation will step into the sustained and rapid growth of the stage period.
(2)The development status and impact of the electrial and electronic industry. In the materials used in the electronic and electrial industry, the application of aluminum profiles is very wide, for examle: used as lighting lampshade parts, etc.; used as motors, transformers and capacitors of the casing of the wind plate, plywood, frame, etc,; used as variety of antennas, shaped waveguide and a variety of car radios, amplifiers, and other electronic equipment shells and their supporting components; used as TV, refrigerator and other household appliances such as frame, handle, etc,; used as cell phones, IPAD and other IT products such as backshells, etc. ...... In a word, aluminum alloy profiles are widely used in all kinds of electronic appliances that are closely related to the people.
(3) The development status and influence of the aerospace industry. Aluminum profiles used in aerospace are relatively high-end, and their main features include: homogenization of organizational properties and high quality, large-scale and integral cross-section, thin-walled and lightweight, and precision of cross-section size and shape size. According to the different uses of aircraft, the proportion of aluminum used is not quite the same. Generally speaking, the proportion of aluminum used in civil aircraft is high, and the proportion of aluminum used in military and scientific research aircraft is relatively low.
