High-performance rare earth magnesium lightweight structural alloy material solves the key problem restricting its wide application of magnesium alloy material.

Release time: 2024-05-07


Compared with ordinary magnesium alloy materials, high-performance rare earth magnesium lightweight structural alloy materials have significant advantages such as high strength, good toughness, heat resistance and corrosion resistance after adding rare earths, which solves the key problems restricting its wide application of magnesium alloy materials. It is the key basic material to promote the lightweight development of China's aviation, aerospace, automotive, rail transit and other fields [5]. China is rich in magnesium and rare earth resources, alloy forming and processing technology is mature, and the market application space is large.

The industrial system of rare earth magnesium alloy lightweight structural materials is complete and can be produced and sold. The future market demand for high-performance rare earth magnesium lightweight structural alloy materials is mainly concentrated in:

① Development and application of short process and low cost preparation technology for high performance magnesium rare earth intermediate alloy and rare earth. Magnesium alloy;

Development of new high performance rare earth magnesium alloy materials for application;

③ Research and development of advanced processing and molding technology and supporting equipment;

④ Improve the rare earth green smelting separation technology and accelerate the promotion and application; in the next 3 to 5 years, the transformation from the military field to the civilian field will be realized, and the market scale will gradually expand. By 2035, the proportion of ordinary magnesium alloy materials will reach 30%.
