Brief Analysis On The Current Situation Of Aluminum Profile In China
Aluminum Profile as the aluminum industry chain downstream processing products, with the technology to enhance the cost of careful control and recycling of resources to enhance the awareness of aluminum production process is also constantly improving the current aluminum enterprises to purchase the main raw materials Is aluminum rods and electrolytic aluminum.
First, the mainstream of aluminum surface technology
At present, the main surface technology of aluminum is divided into: anodic oxidation, electrophoretic coating, powder coating, wood grain transfer, fluorocarbon coating and polishing (divided into mechanical polishing and chemical polishing two, chemical polishing the highest cost, the price Also the most expensive)
Second, aluminum classification and related applications
Aluminum Profile through the different composition of aluminum and the composition of the alloy composition can be divided into different 1 to 9 series, of which 6 series of aluminum is currently on the market more popular products, 6 series of aluminum alloy main alloy ratio is Magnesium, silicon.
6 series of aluminum can be divided into two categories:
(1) building profiles
This type of profile is mainly used in the construction field, which is mainly made of doors and windows and curtain wall.
(2) industrial profiles
This type of profile is mainly used in aerospace, rail transportation, radiators and general industrial aluminum required.
Third, China's aluminum market analysis
1, the national aluminum market evolution process
Since the reform and opening up, China's aluminum industry has been booming. Product structure has been mainly building materials, but with China's industrial level and scale of continuous improvement, industrial timber production has also increased year by year. In the automobile manufacturing, rail transportation, electric power, machinery and equipment manufacturing industry, electronics and other industries, the rapid increase in the demand for aluminum, new products, new technology, new uses of Aluminum Profile continue to emerge, and promote technological progress and sustained and healthy development of the industry The With the rapid development of China's large-scale infrastructure investment and industrialization process, aluminum as the field of construction and machinery industry in the field of important application materials, its industry-wide production and consumption of rapid growth, China has also become the world's largest Aluminum Profile production base and consumer market.
At present, aluminum is moving in the direction of large cross section, thin wall thickness, high dimensional precision, complicated cross section and exquisite appearance. In order to produce these products, many large extruders are also put into use. For example, high-speed train with aluminum, CRH2, CRH3, CRH5 EMU body are Aluminum Profile. Large section of hollow aluminum extruder body mechanical properties and cross-section has strict requirements, and to be able to squeeze into a variety of complex large cross-section materials, domestic manufacturers generally use more than 60MN tons of extruder to produce. At present, the state also introduced the relevant policies to support the development of aluminum in the direction of sophisticated, such as China's "second five" plan to vigorously develop aluminum finishing products, focusing on supporting technological transformation and strategic development of new industries.
The technical level of aluminum has been increasing, such as powder coating, fluorocarbon spraying, organic and inorganic dyeing, electrophoretic coating, mechanical and chemical polishing, surface drawing and other advanced technology has long been widely grasped in the industry. At the same time, wood grain transfer processing, heat insulation profiles and other new technologies have begun to widely used, effectively enhance the Aluminum Profile, energy saving, environmental protection effect. With the continuous improvement of industrial profiles, varieties continue to enrich, many new processes are also emerging.
2, the current profile of the distribution of Aluminum Profilein scale of production and processing of aluminum enterprises nearly 800, of which the top three provinces are: Guangdong Province, accounting for 24% of the total; Shandong Province, the total Of the 16%; Jiangsu Province, accounting for 13% of the total.
South of Guangdong Nanhai area of the Pearl River Delta, eastern Jiangsu and Zhejiang area of the Yangtze River Delta, northern Liaoning and Shandong area of Bohai Bay is the construction of aluminum industry three developed areas, the formation of private aluminum business group.
