China is an aluminum producer and consumer, and the overall proportion is close to 50%. However, at present, the production capacity of ordinary products in China's aluminum processing industry is excessive, while the production capacity of high-tech, high-precision and high-quality products is seriously insufficient. There is still a gap between the level of process equipment and design and manufacturing capabilities in aluminum-lithium alloy technology, all-aluminum body, aerospace aluminum and engine manufacturing.

The main reasons are: First, the overall technological innovation capability of the aluminum processing industry is insufficient; second, the lack of independent core technology and independent brands, China Aluminum Industry has not developed many new materials independently, and in the development of new alloys, it basically tracks foreign products and is independent. The development is almost blank, especially high-tech materials such as aluminum aerospace, which has high technical content and important developmental strategic significance, and most of them rely on imports.

Especially in the aspect of aluminum alloy, it is basically monopolized by USA Aluminium Company, Alcan Aluminum Company, German Cruise Aluminum Company and Japan Light Metal Company. The aluminum materials used in China's C919 large aircraft and ARJ21 regional passenger aircraft are provided by USA Aluminum. The ARJ aircraft is mainly made of aluminum alloy. The weight of the aircraft is 25 tons. The quality of aluminum parts accounts for 75% of the net mass of the aircraft. At 42 tons, the total mass of aluminum workpieces accounts for 65% of the total net mass of the aircraft. In total, there are about 24 kinds of metal materials in China that need to be imported, and 17 of them are provided by Japanese companies, accounting for 70.8%.

Transformation and upgrading, look at the exploration of aluminum in China's aluminum enterprises

It is estimated that 80% of aviation aluminum sheet procurement opportunities will be given to local Chinese enterprises. Based on the installed capacity and R&D investment of existing aluminum processing, the proportion of domestic aluminum materials will increase to 35% in 2018, and will increase to 75% in 2022. In the year, all localization will reach 95%.

From this point, it can be seen that there is still a lot of space for the production of high value-added aluminum products in China. Therefore, China's electrolytic aluminum de-capacity work must be forward-looking, to complete the systematic upgrading of the industry in the process of de-capacity, in order to achieve long-term leading position in the competition.

Nowadays, China's electrolytic aluminum enterprises have embarked on the road of product upgrading. Many domestic aluminum enterprises have made great achievements in the development and production of aluminum materials in recent years.

In December 2016, after nearly 10 years of research and development and special research, Chinalco Southwest Aluminum Zui became the first enterprise in China to master the production technology of high-strength and high-tough 7050 aluminum alloy pre-stretched thick plates. The successful development and application of this technology has completely broken the long-term Western blockade of manufacturing technology in key areas of China, and has enabled China's related manufacturing technology water to enter the first stage.

As one of the representative enterprises of China's manufacturing industry, China Zhongwang, after more than 20 years of industry accumulation, China Zhongwang has developed into an industrial aluminum extrusion product R&D manufacturer in Asia, and has gained access to railways, automobiles, ships, aviation, etc. A number of certifications including the industry. It is one of the suppliers of the “Revival” vehicle body aluminum profile. At the same time, it is actively exploring the aerospace aluminum field. It has launched the “7075 Aviation Extrusion Bar” for the specifications, characteristics and strict quality requirements of aluminum profiles. "R&D project."

Shandong Nanshan Aluminum Industry Co., Ltd. is a large-scale enterprise affiliated to Nanshan Group (the top 500 Chinese enterprises). As the only listed company in China with aluminum as its main business, it has the only short-distance Zui complete aluminum industrial chain. The company's scale and output continue to be stable. The forefront of large aluminum industry enterprises. Since 2012, Nanshan Aluminum has been developing automotive aluminum and aerospace aluminum panels with high technical barriers.

After scientific planning and systematic demonstration, in early 2010, Yulian Group's annual production of 600,000 tons of aluminum precision deep-processed aluminum project officially started construction. The main products are imported cans, cans, cans, double-zero aluminum foil blanks for packaging and electronics, anodized materials for mobile phones and notebook computers, traffic aluminum for automobiles and ships, and bars and poles. Used in new packaging, electronic appliances, transportation and green building. In November 2016, Yulian Group's 600,000-ton high-precision aluminum project was completed and put into production.

In 2018, on November 28, Luoyang Wanji Aluminum Processing Co., Ltd. 10 tons of 1.0 mm thick mirror aluminum plate products were successfully launched. After testing, the surface gloss, ductility and reflectivity of the products were in line with customers. Claim. Mirror aluminum plate is mainly used in the decoration field of car logo, lamp reflector, instrument panel, etc. The price is only one-third of the price of stainless steel, and the market prospect is broad. In the past, mirror aluminum panels were produced by three Japanese manufacturers, Sumitomo, Aluminium, and Austrian Alcoa. Wanji aluminum processing mirror aluminum plate was successfully developed, breaking the technical blockade in this field.

Shandong Weiqiao Aluminium Power Co., Ltd. and Suzhou University signed an agreement to establish an aluminum material manufacturing and application technology research institute to promote the manufacture and application of new aluminum alloy materials, strengthen collaborative innovation in the field of advanced aluminum processing, and accumulate greater development potential and momentum. To enhance the independent innovation capability, market competitiveness and social influence of both parties in the industry. Focus on the development of high-strength, high-toughness and high-resistance 6xxx new aluminum alloy materials for automotive and new energy vehicles, high-performance cast aluminum alloys and intermediate alloys, new packaging materials and aluminum alloy materials for electronic appliances.

Nowadays, the aluminum industry is in the stage of conversion of old and new kinetic energy. It is difficult to obtain higher market profits by taking the volume. It is necessary to take a high-tech road to maintain the long-term development of the company. The production of aluminum is only the first step in the industry upgrade. In order to achieve a complete upgrade of electrolytic aluminum in China, it is required that electrolytic aluminum enterprises are not only satisfied with simply providing products, but more importantly, providing perfect and accurate aluminum manufacturing solutions for high-tech industries.
