Magnesium alloy is known as the "green material of the 21st century" due to its lightweight and superior performance, and has received great attention worldwide. Extensive research has been conducted on its applications both domestically and internationally.

China is a major producer of magnesium resources in the world, and currently, the world's primary magnesium production mainly comes from China. In recent years, the overall operation of China's magnesium industry has been stable, with continuous growth in production and export volume. In 2019, China exported approximately 452000 tons of various magnesium products throughout the year, a year-on-year increase of 10.2%, accounting for 46.6% of China's magnesium production; According to statistics from the General Administration of Customs, in 2020, despite the impact of the epidemic, the export volume of six types of magnesium products under different tax codes in China still totaled 393800 tons.

The concentration of China's magnesium alloy industry is relatively high. From a regional distribution perspective, Shanxi and Shaanxi mainly produce raw magnesium and magnesium alloys, while Guangdong and Jiangsu mainly produce magnesium die-casting and deep processing; From the domestic market perspective, primary magnesium in China is mainly distributed in Shaanxi, Shanxi, Ningxia, Xinjiang and other regions.

Magnesium alloy is currently the lightest metal structural material in practical applications. With the continuous promotion of energy conservation and emission reduction, lightweight has become an important consideration factor in product design in industries such as aviation, aerospace, automotive, rail transit, and 3C products (computer, communication, consumer electronics). The use of various lightweight structural components, components, and materials is becoming increasingly widespread. At present, the downstream demand for magnesium alloys in China is mainly in the automotive and 3C product manufacturing industry, with a market share of over 80%.

Magnesium alloy has excellent casting performance, with magnesium alloy castings accounting for 40% of all magnesium alloy processing and forming process parts, and die castings accounting for more than 65% of the total magnesium alloy castings. In recent years, the upgrading trend of China's magnesium alloy material industry has been obvious, and important breakthroughs have been made in the processing technology of rare earth magnesium alloys, large-sized cast rods, and large complex parts. The developed high-strength magnesium alloy large-sized complex castings and high-strength heat-resistant magnesium alloy large-sized extruded profiles/forgings have reached the world's advanced level.

Although China has made significant progress in lightweight production at present, there is still a significant gap compared to foreign countries in terms of product research and development, manufacturing, and application popularization. The industrial application of magnesium alloy materials has become a research hotspot in the field of metal materials in recent years. With the vigorous promotion and use of new energy vehicles, the construction of high-speed railways, the accelerated breakthrough of the aerospace industry, and the rapid development of 5G networks, the research and application of magnesium alloys will usher in greater opportunities and market prospects in the coming years. In the future, the research and development of cutting-edge and ultra-high performance magnesium alloy materials, as well as the improvement of precision machining capabilities for high-performance and low-cost magnesium alloy complex parts, will be important development directions, thereby promoting the lightweight development of equipment. The localization rate of magnesium alloy materials for major national engineering projects will also approach 100%.
