China should attach great importance to the strategic position of magnesium alloy industry

China should attach great importance to the strategic position of magnesium alloy industry

Magnesium alloy is known as "21st century green environmental protection structural material". It has very good application performance and is currently the lightest metal structural material. It has high specific strength, high specific stiffness, good shock absorption, and the ability to withstand impact loads Large size, excellent electromagnetic shielding performance, no biological toxicity, good corrosion resistance to organic matter and alkali, and rich resources. With the continuous improvement of processing technology, the scope of application of magnesium alloys has expanded rapidly, and the market demand has continued to grow. The rapid development and expansion of the magnesium alloy strategic industry is of great significance to the development of my country's national economy and national defense technology industry.
