How about the tungsten alloy made of tungsten powder?


What’s tungsten powder?

Tungsten powder

Reduced with hydrogen in either a four tube muffle furnace (using tungsten dioxide as the raw material) or multi-tube furnace (using tungstenoxide). It has a particle size of 0.6 to 30 microns. It can be divided into medium, fine and coarse particles. It is determined using the national standard for impurities. The impurity content is determined by the national standard. Preparing tungsten powder using hydrogen reduction generally involves two stages. In the first, there is a reduction in tungsten trioxide into tungsten dioxide at 500 – 700 oC. In the second stage of the process, tungsten bioxide is reduced to powder at 700 – 900 oC. The reduction reaction takes place in either a rotary or tubular electric furnace. It is important to know the performance characteristics of reduced tungsten – such as its purity, size and composition. It all depends on how the reduction is done. Tubular furnaces can reduce tungsten to a powder. The process parameters that determine the reduction rate include the temperature, amount of tungsten dioxide in the burned boat, burning boat speed, flow rate of hydrogen, and moisture in hydrogen. As the temperature decreases, the tungsten powder’s particle size becomes larger.


Standard properties of tungsten-powder


The oxygen content in tungsten powder should not exceed a specified limit. There are also certain specifications regarding the impurity level. Commonly, tungsten is 210 times smaller than the Fisher size m.m. Polygonal particles are the most common form of tungsten. The specific surface area of the tungsten powder, its bulk density and tap densities also have a range. These properties have a direct impact on the production of high-quality tungsten metal products and the quality and purity of the tungsten powder. Tungsten powder has three types: purity, size and uses. In the beginning, tungsten-reduced tungsten slurry was divided into three grades according chemical purity. Japan established the JISH2116-1979 industrial standard for Tungsten Powder. France, Britain and many other countries have their own unified standards for tungsten pulver. For tungsten powder manufactured in China, Technical Conditions for Hydrogen Reduction (GB3458-82) has been formulated. This standard specifies the properties of tungsten powder and their classification grades. The standard specifies inspection procedures, acceptable rules, packaging and transportation, as well as storage. You can request tungsten powder to be made according to your requirements.


Use of tungsten powder


Processing powder metallurgy items and tungsten alloys begins with tungsten powder. You can make wires and tubes from pure tungsten powder. Mixed tungsten powder can make a number of different tungsten alloys. These include tungsten molybdenum, tungsten-rhenium and tungsten copper. The tungsten-powder can also be used in making tungsten carbide powder. This is useful for turning tools, drilling tools, and other tools that use cemented carbide such as milling cutters.


The price of tungsten dust


Price will depend on the quality and size of the tungsten powder particles. The purchase volume may also have an effect on how much tungsten powder is purchased. Large quantities of small amounts will result in a lower price. On our official website, you can see the cost of tungsten powder.
