Chinese metal powder production status in recent years

Iron base, copper base metal powder as its raw material must achieve a great development. China iron production plant into production statistics has reached 30 units (more than a dozen small-scale production did not enter the statistics). Iron-based powder production has exceeded 2.2 million tons. Statistics iron production is targeted to reach the national standard iron products manufacturing plant. Annual output of ten thousand tons has reached eight iron plant. Mainly from the iron increment of a certain production scale iron production plant. Chinese iron-based powder in 2005 has reached 224,950 tons, if not into the statistics with more than a dozen iron plant production, estimated annual output of more than 250,000 tons iron. In 2005 China exported 28,000 tons of iron-based powder, mainly exported to Japan and other countries. Imports of iron 25,000 tons, mainly imported iron iron-based pre-mixed.Copper-based metal powder production rose steadily, due to volatile raw material prices cause, copper metal powder production growth slowed down. Copper has replaced part of the oxidation-reduction copper powder market. National production of copper-based metal powder over Japan.The last three years is a metal powder manufacturing industry's largest investment in the period, nearly three million investment to bring 65,000 tons of iron powder and 1000 tons of copper powder increment increment. China is also a metal powder manufacturing period of great development, preliminary estimates, China is iron-based powder has nearly 28 million tons of production capacity, copper and copper alloy powder with 11,000 tons of production capacity.Iron base, copper base metal powder application has been further expanded, manganese powder but also increase the driving force to promote one of its production. Iron into the soft magnetic material industry, faster, metallurgy, chemical industry, environmental protection and other fields are also expanding the application of iron, and even edible flour with iron experiments are under way. With the oil-bearing powder metallurgy production center shifting to China, copper and copper alloy powder is increasing.In recent years, China's major copper-based metal powder production plant in the basic structure of copper-based powder varieties are: copper powder, copper powder production accounted for 65% of atomized copper alloy powder, 30%, the rest of redox copper, minor Sintered copper alloy powder, copper powder and other chemical reduction. Industrial production of iron powder metals technology with China are to expand the varieties of iron powder metals, boron powder improve product quality is the current Chinese iron-based powder production plant is the main task. The traditional copper-based metal powder production methods - electrolysis, atomisation in China has become more mature, oxidation-reduction process, a slight sintering of copper-coated iron technology has been out of the pilot phase, there is mass market.Production of copper-based metal powder major consideration product performance. Such as powder particle size, particle shape, bulk density, mobility, etc.. But also consider the production of environmental protection, cost and other factors. According to different national conditions, copper powder, 22,000 tons per year in North America, 88% are using water spray + redox process manufacturing. Japan and China, most of the copper-based metal powder is manufactured by electrolysis. With increasing the degree of environmental protection, electrolytic copper metal powder Preparation of pressure. Not to blindly expand production capacity of electrolytic copper powder. Development of water spray + redox system and other new technology to take copper is copper-based metal powder industry development. Source:http://www.mhcmp.com
