The role of metal materials in the development of science and technology in China in the new period

Metal materials play a vital role in the development of science and technology in China. With the development of science and technology, the requirements for metal materials are getting higher and higher, including high strength, light weight, high temperature resistance and corrosion resistance. The development of metal materials has promoted the progress of all walks of life, such as aerospace, automobile, electronics, energy and other fields.

In the aerospace field, metal materials are widely used, such as aluminum alloy and titanium alloy. These metal materials not only have the characteristics of high strength and light weight, but also have good high temperature resistance and corrosion resistance, so they are widely used in the aerospace field. In addition, metal materials are also widely used in automobile, electronics, energy and other fields. For example, the application of copper alloy tubes in automobile and power station condenser tubes is growing rapidly, and the application of magnesium alloys in automobile, electronic devices, sports equipment, office supplies and other industries is also growing rapidly.

In addition, the processing and forming technology of metal materials is also facing new problems and challenges. For example, the processing and forming technology of copper materials includes both traditional processing technologies such as extrusion and drawing, and new processing technologies such as combined drawing and disc drawing for processing thin-walled smooth tubes for air conditioners. The application of these new processing technologies not only improves the quality and efficiency of pipes, but also promotes the application growth of copper materials in refrigeration and air conditioning industry. In addition, the processing technology of magnesium alloys is also facing new problems and challenges, such as the development of semi-solid processing technology and the research and development of plastic processing technology.

Generally speaking, metal materials play a very important role in China's scientific and technological development, which not only provides important support for China's economic development, but also makes positive contributions to China's scientific and technological progress. With the continuous progress of science and technology, the application field and processing technology of metal materials will continue to develop and improve.
