Non-ferrous metals are essential materials and important strategic materials for the national economy, the daily life of the people, the national defense industry, and the development of science and technology. Agricultural modernization, industrial modernization, national defense and the modernization of science and technology are all inseparable from non-ferrous metals. For example, cutting-edge weapons such as airplanes, missiles, rockets, satellites, nuclear submarines, and the components or components required for cutting-edge technologies such as atomic energy, television, communications, radar, and electronic computers are mostly made of light metals and olefinic metals in non-ferrous metals; There is no nickel, cobalt, tungsten, molybdenum, vanadium, niobium and other non-ferrous metals and there is no production of alloy steel.
The use of non-ferrous metals in certain applications (such as the power industry, etc.) is also considerable. Many countries in the world, especially industrialized countries, are competing to develop the non-ferrous metal industry and increase the strategic reserve of non-ferrous metals.
