Introduction: the position of the national defense science and Industry Bureau, the first confirmed military field is writing "the national defense science and technology industry 2025". The great strategic value of rare metals is mainly reflected in the manufacturing of key parts of national defense, aviation and aerospace. So what is the use of rare metals in the national defense science and technology?
Xu Dazhe, director of the Bureau of science, technology and industry for national defense, said recently that according to the "national defense science and technology industry 2025 and science, technology and industry for national defense, military and civilian fusion" 45 "planning preparation, and promote China's equipment upgrade. In the "China made 2025" strategy, the industry is actively docking and the development of the industry planning. The national defense science and Industry Bureau, the first confirmation of the military field is the preparation of the defense science and technology industry 2025". The great strategic value of rare metals is mainly reflected in the manufacturing of key parts of national defense, aviation and aerospace. So what is the use of rare metals in the national defense science and technology?
Aviation engine as a cutting-edge technology in the field of defense representatives, the industry is the most reflect the national level of defense and defense capabilities, known as the crown jewel of the modern industry, can act as a typical project of military integration and intelligent manufacturing, and to implement innovative driven strategy to play a leading role, is China made ten key projects, so it will be the focus of the national defense science and technology industry 2025.
Aero engine with high complexity and precision of thermal mechanical properties, long time in high temperature, high strength, high corrosion of the most complex and harsh environment, which requires the use of some high strength, high temperature, low temperature, quality and toughness of the material. Rare metal indium, germanium, tungsten, molybdenum, vanadium and rare earth metals are important materials for the manufacture of aviation materials.
Indium is a very rare rare metal, which can be used as a metal clad layer or with other metals to enhance the corrosion resistance of engine bearings. Tungsten is the most hard material in nature except diamond, it is the foundation of all kinds of hard alloy, it is the best material for producing all kinds of high speed steel and machine tools, drills, etc. it is an important tool for the production of aerospace parts. With heat resistance and the strength of the turbine blade is composed of rare metals such as tungsten, nickel and rhenium super alloy products, which contains about 6% of tungsten.
Germanium is the essential equipment of the aerospace vehicle infrared tracking instrument lens material, China and the United States is the main producing countries, but for a long time, China to account for 41% of the world's reserves of 70% of the world's demand. For this metal is extremely scarce, ready to state purchasing and storage and storage for the long-term development of the country folk.
