Profile:
Aluminum processing, processing aluminum billet ingots into materials with plastic processing methods, the main methods are rolling, extrusion, drawing and forging. In recent years, China's aluminum processing industry is facing gradually tightening policies, declining profitability and trade friction, etc., to accelerate the transformation and upgrading of the development of the aluminum processing industry has become the top priority.
I. Aluminum processing definition and industry chain
Aluminum processing, using plastic processing methods to process aluminum billet ingots into materials, the main methods are rolling, extrusion, drawing and forging. China built a large aluminum processing plant in the mid-1950s, forming a more complete industrial chain. Besides, the product has been serialized into seven alloy systems which could be made into plates, strips, foil, tubes, bars, profiles, wire and forgings (free forgings, die forgings) eight types of products.
II. Aluminum processing industry development policy
Aluminum processing industry in China has received great attention from governments at all levels and key support from the national industrial policy recent years. The country has issued a number of policies one after another to encourage the development and innovation of the aluminum processing industry, "Additive Manufacturing Standard Pilot Action Plan (2020-2022)" "Guidance on Expanding Investment in Strategic Emerging Industries to Foster and Grow New Growth Points Growth Poles" "New Material Standard Pilot Plan (2018-2020)" and other industrial policies have provided a clear and broad market prospect and provide a good production and operation environment for enterprises. The details are listed as follows.
III. Current development of the aluminium processing industry
Aluminum processing is the processing of aluminum, the raw material electrolytic aluminum through melting, rolling, extrusion and surface treatment and other processes and procedures, the production of aluminum profiles, tubes, bars and other extruded materials, plates, strips, foil and other flat-rolled materials, as well as casting materials and other types of aluminum.
1. Aluminium material
Recent years, China's aluminum processing industry has faced problems such as gradually tightening policies, declining profitability and constant trade frictions. With the country's supply-side structural reform of the aluminum processing industry, technological progress in the aluminum processing industry, aluminum smelting industry has been developing towards high quality. China's aluminum production reached 49.669 million tons by October 2021, up 9.3% year-on-year.
2. Market share
Looking at the structure of aluminum in China, the highest proportion of aluminum profiles is 53%, followed by aluminum sheet and strip and foil in order of 30% and 10% respectively.
3. Market segmentation
(1) Aluminum sheet and strip
With the booming development of downstream industries such as transportation and construction, the market size of China's aluminum processing industry is growing rapidly, with the total output of aluminum sheet and strip in China being about 11.4 million tons in 2017 and 11.9 million tons in 2020, with a compound annual growth rate of 1.44%. It is expected that the output of aluminum sheet and strip in China will reach 12.3 million tons in 2022.
(2) Aluminum foil
Data show that China's aluminum foil production increased from 3.65 million tons in 2017 to 4.15 million tons in 2020, with an average annual compound growth rate of 2.53%. China Business Industry Research Institute predicts that China's aluminum foil production will reach 4.57 million tons in 2022.
(3) Aluminum alloy
Aluminum alloy has a series of excellent characteristics, such as easy processing, light quality, good electrical conductivity, etc., and its relatively low cost makes it an alternative to steel, copper and other materials. Data show that China's aluminum alloy production fluctuates more obviously, but the overall growth trend is maintained, and the cumulative output of China's aluminum alloy will be 9.636 million tons in 2020, with a compound annual average growth rate of 6.75% from 2017 to 2020, and the output of aluminum alloy is expected to reach 10.976 million tons in 2022.
(4) Aluminium profiles
Aluminum profiles are mainly used in the construction field and industrial field, and can be divided into two categories: construction profiles and industrial profiles. Construction profiles are mainly used in the construction and real estate industries, and among the sub-species consumption fields of construction aluminum profiles, aluminum alloy doors, windows and curtain wall profiles account for the main part of them. Industrial aluminum profiles are mainly used in the four fields of transportation, mechanical and electrical equipment, durable goods and electronic appliances.
4. Market concentration
The overall concentration of the aluminum processing industry is low, but the CR6 of the aluminum processing industry has been on a growth trend from 2016-2020, growing from 10.98% in 2016 to 14.42% in 2020.
