R & D INNOVATION

Study the essence,Principle of inquiry

With the support of a professional team engaged in basic research and application research, the company has successively undertaken the research tasks of national development and Reform Commission, Ministry of science and technology, provincial and municipal major projects and industrialization projects, and obtained a number of research results and invention patents in the field of magnesium, covering high strength, heat resistance, low temperature, corrosion resistance More than 30 kinds of high toughness and flame retardant magnesium alloys meet the needs of aerospace, rail transit, automobile, machinery, military and other industries.

R & D ADVANTAGES

In the 21st century, human beings put forward new requirements for metal structural materials: the research and development of new materials should not only be able to adapt to the development of high technology and meet the needs of human beings' high-quality life, but also require rich resources, high efficiency, low energy consumption and easy recovery, which is conducive to sustainable development; it must be able to meet the increasingly stringent requirements of environmental protection laws and regulations in the future to enter the market and application smoothly.

China is a big country of magnesium resources. We should take advantage of this condition, improve the value of magnesium resources, adjust the industrial structure, expand the application of magnesium and lead the development of magnesium industry...
