China Powder Metallurgy industry started in the early 1950s, basically with those of Japan, but in terms of its growth rate, significantly behind Japan, and North America, Europe, the gap is even greater.
Experienced half a century of business development, on the basis of independent development, through the "75", "85", "95" technological innovation and technology transfer, that has developed a complete range of products, there is a certain scale of production and emerging scientific and technological level of the industrial system. In particular, the past two decades, China's mechanical parts powder metallurgy industry has changed greatly; equipment level has been greatly improved and enhanced, some companies have formed the world's advanced and advanced CNC press powder sintering furnace, with a modern mold manufacturing equipment and testing equipment, which greatly increases the efficiency of development and research, has dramatically changed the corporate image, enhance the resilience of the enterprise market and participation in international competitiveness. At present, for automotive, motorcycle, engineering machinery, household appliances, electronics, electrical equipment, defense industry, power tools and other industrial sectors to provide support.Total production of powder from China and production system, boron powder despite the second only to Japan, but the product development capabilities, technical performance, product quality and manufacturing standards and its competitiveness on international markets to see, and powder metallurgy world powers - U.S., Japan, Europe than the gap even more. Mainly as follows: 1 product convergence, constitute unreasonable. The lack of high-performance products. Car engines, shock absorbers, transmissions used in high strength, high density, high-precision powder metallurgy parts, high precision miniature oil-bearing, high-performance friction materials and other products can not meet demand. (2) low performance, poor reliability. At present, China's production of powder metallurgy iron-based structural parts, in general, as sources of raw materials powder and more, quality management, production and technical issues, product quality is not enough and stability, due to weak product development, silicon powder product performance and reliability radiation has yet to be enhanced and competition. 3 product innovation and self-development capacity is weak, can not meet the rapid development of automobile manufacturing, electronics, office equipment and developing new fields of communications, cutting tools, fitness, biotechnology, home, office automation, material transportation and other support needs of high-tech industries. At present, FAW, SAIC company's cars are mostly used in powder metallurgy parts with auto parts imports.In order to meet automotive environmental protection, energy saving, lower manufacturing costs and improve performance and other requirements, the development of automobile engines, transmissions and other key used thousands of powder metallurgy parts, such as the exhaust valve seat, rod, ABS ring, the types of gears, sprockets, automatic transmission parts, cams, etc. Powder metallurgy parts and car manufacturing is now an important foundation for auto parts parts. Powder metallurgy technology has become the automotive and automotive parts manufacturing industry to improve and enhance the quality, development of new materials, new products, reduce production costs and enhance competitiveness of the core technologies.
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
