In addition to tungsten powder has certain requirements on impurity content, oxygen content should be controlled in a certain range. Commonly used tungsten powder size is generally average particle size 2 ~ 10 mu m.polygonal tungsten powder particle shape.In addition,the tungsten powder surface, bulk density, tap density also changes in a certain range.. has a direct impact on the quality and properties oftungsten powderon the production of tungsten materials and tungsten powder metallurgy products, especially the influence of purity and granularity of tungsten powder is more obvious. And according to the classification of purity and granularity and different purposes.The earliest production of tungsten powder Huachang company is according to the chemical purity of hydrogen the reduction of tungsten powder is divided into three levels; Japan has formulated the "tungsten powder and tungsten carbide powder according to the industry standard (JISH2116-1979); Britain, France and the former Soviet Union and other countries have a unified national standard of tungsten powder tungsten powder.Chinese industrial production in 1982 developed a technology of hydrogen reduction of tungsten powder. A > (GB3458-82). The standard specifies the properties of tungsten powder and classification number. And the test method, inspection rules, packaging, transportation and storage projects are made clear. For special purposes and military special tungsten powder production plant, according to the production requirements of the users.

The use of tungsten powder

Tungsten powder is the main raw material processing powder metallurgy of tungsten alloy products and the pure tungsten powder can be made into silk, rod, tube, plate shape and material processing products. Tungsten powder and other metal powder, can be made into all kinds of tungsten alloy, such as tungsten alloy, tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy.Another important application of tungsten powder is made of tungsten carbide powder, and preparation of cemented carbide tools, such as turning, milling, drilling and other molds.

The market situation of tungsten powder

At present, affected by the whole market of tungsten powder, the market is still light, but relatively speaking, the market price range slowly toward the low price, volatility is not too large, due to the continued weak demand from downstream enterprises, so the purchase is unlikely, according to production orders, fewer new orders and new customers,with the increase of production and production. The upstream and downstream businesses operating enthusiasm is low, wait-and-see attitude intensifies, some manufacturers of tungsten powder due to the current market price is slightly lower, the funds can flow under the condition of not only a few sellers, or sell the goods, do not rush shipping, hope prices can be stabilized to improve.Because of the powder size and structure is different,the actual turnover the price may be slightly different, and different applications have different structure of powder,the corresponding product structure and profit are different, like tungsten bars, tungsten plate and other primary products, the profit is relatively low for airlines The empty space and special features in the field of alloy products, has a relatively good development prospect. At present, enterprises can according to their own characteristics, to seek new product development, and constantly improve the proportion of these high-end products for enterprise products, feedback to the enterprise benefit,enhance the market share, to occupy the advantage in the market competition.
