"Powder metallurgy" as a green manufacturing technology for material saving, energy saving, environmental protection, short process precision and complex parts has become a must for new material strategy. Han Wei, secretary-general of the Strategic Alliance for Technology Innovation in the Powder Metallurgy Industry, told the Science and Technology Daily that the powder metallurgy products are widely used in key industries such as metallurgy, machinery, automobiles, motorcycles, home appliances, textiles, chemicals, environmental protection and energy. The recent nanotechnology process and nano-powder products have also been added to the emerging field of powder metallurgy, highlighting the importance of new powder metallurgy technologies, new processes and new materials. Han Wei said that powder metallurgy technology has always been a topic of material science in the world. It can be expected that powder metallurgy will play a more important role in the fields of national defense military, modern automobile, high-end equipment for machine tools, new-generation information technology basic devices, new medical equipment, and energy.
Since the 21st century, China's powder metallurgy industry has developed rapidly, forming "steel and non-ferrous metal powders", "powder metallurgical machinery parts", "refractory metals - hard alloys and cermets", "superhard materials and tools" The five major sub-areas of rare earth permanent magnets and soft magnets prepared by powder metallurgy process, from 2002 to 2014, the output of iron powder and alloy powder reached 400,000 tons from 100,000 tons, accounting for one quarter of the world's total steel powder production.
The "Twelfth Five-Year Plan" faces new transformation challenges. In Han Wei's view, the powder metallurgy industry urgently needs to integrate forces, form a new cooperation mechanism, open up the upstream and downstream industrial chain, combine production, study and research, jointly solve key technical problems facing industrial development, and accelerate the innovation of new materials and new technologies. Break through the core technology of high-end products, enhance core competitiveness, promote the optimization and upgrading of its industrial structure, and provide much-needed basic material support for other strategic emerging fields.
