What are the problems in the field of aluminum alloy materials in my country?

my country is a major producer and consumer of aluminum alloy materials. Aluminum alloy materials are widely used in transportation, ocean, aerospace and other fields, especially in some lightweight key components in the fields of automobiles, aircraft, aerospace, and ships. Irreplaceable. The vast majority of domestic aluminum alloy materials belong to low-end products, with high energy consumption, low efficiency, high cost, and low added value. It is difficult to change the situation of vicious competition, and some high-end products still need to be purchased at high prices from abroad. This is undoubtedly It hinders the pace of upgrading of our manufacturing industry. Although our country has significant advantages in the fields of communications and high-speed rail, with the intricate changes in the international situation, the risk of getting stuck in key materials fields has become increasingly prominent, and independent innovation is urgent. Under the new industrial situation, the development of green and intelligent preparation and processing technology of high-end aluminum alloy materials is of great strategic significance to support the sustainable and high-quality development of my country's key manufacturing industries. There are problems in the field of aluminum alloy materials in my country. It is worth noting that although my country's aluminum alloy materials have made outstanding achievements in terms of industrial scale and technical level, the construction of my country's modern industrial system started late and has a weak foundation. It is difficult to catch up with developed countries, which is quite part of the key. Basic materials and core components are still not self-sufficient. my country will be a major demand country for key basic materials for a long period of time in the future, and the demand for the quantity and types of such materials will continue to increase. However, high-end materials do not account for a high proportion of the industrial system, the original innovation is relatively small, and the basic common key technologies and intensive processing technologies are insufficiently developed. Alcoa has 30,000 patents. In contrast, Chinese companies have few original patents and hundreds of commonly used brands, but few of them are developed by China. At the same time, the consistency, uniformity, and stability of product quality are not high. . The quality stability of pre-stretched thick plates and skin plates for large aircrafts, and passenger car panels needs to be improved, and some high-end aluminum plates, strips, and foils still rely on imports. In addition, the extensive development of my country's aluminum alloy material industry is a serious problem. Although the industrial scale is growing fast, there is little research and development. The technological innovation of 'production, study and research' integration is weak, and universities and enterprises cannot give play to the advantages of collaborative innovation. Therefore, it is very important to gradually promote the development of related research and industries towards high-quality, high-innovation, and high-efficiency. In accordance with the 'Guiding Opinions of the State Council on Promoting International Cooperation in Production Capacity and Equipment ManufacturingThe establishment of the factory, while actively learning the advanced technology and management experience of foreign companies, continuously optimizing products and equipment, and enhancing international competitiveness.
