What is tungsten powder?
Tungsten powder is reduced with hydrogen in a four-tube muffle furnace or a multi-tube heater using tungsten oxide as the raw material. The fragment dimension ranges from 0.6-30 microns. It is mainly divided into coarse, medium and also fine fragments, silver grey powder. The contamination material is based upon the nationwide standard. It is prepared by hydrogen decrease of tungsten trioxide or ammonium para tungstate. The process of preparing tungsten powder by hydrogen decrease is normally split into 2 phases: the first stage is the decrease of tungsten trioxide to tungsten dioxide at 500 ~ 700oC; In the 2nd phase, tungsten dioxide is decreased to tungsten powder at 700 ~ 900oC. The reduction reaction is generally accomplished in a tubular electric heating system or a rotating heating system. The performance of the decreased tungsten powder (such as pureness, bit size, bit dimension composition, and so on) mostly depends on the reduction procedure. When tungsten powder is decreased in a tubular furnace, the primary process criteria that impact the decrease price are the decrease temperature, the quantity of tungsten oxide in the burning watercraft, the burning boat moving rate, the flow price of hydrogen and also the moisture web content in hydrogen. With the rise of the decrease temperature level, the particle size of tungsten powder becomes rugged.

Characteristics and standards of tungsten powder
In addition to certain demands for the pollutant content of tungsten powder, the oxygen content must be controlled within a specific variety. The fragment dimension of typically used tungsten powder is generally 2 ~ 10 of the ordinary Fisher size μ & mu; m. Tungsten powder is in the form of polygonal bits. Furthermore, the particular area, mass density and also tap thickness of tungsten powder likewise vary within a particular variety. The buildings of tungsten powder directly affect the production of tungsten materials as well as the high quality of tungsten powder metallurgy items, specifically in purity as well as fragment dimension. Tungsten powder is classified according to purity, particle dimension, and various usages The earliest production of tungsten powder is to divide hydrogen-reduced tungsten powder right into 3 qualities according to chemical pureness; Japan has actually created the commercial requirement of Tungsten Powder and also Tungsten Carbide Powder (JISH2116-1979); Britain, France, the previous Soviet Union as well as various other nations all have actually combined national criteria for tungsten powder. In 1982, the Technical Conditions for Hydrogen Reduction of Tungsten Powder (GB3458-82) was developed for tungsten powder produced in China. This conventional defines the residential properties as well as classification qualities of tungsten powder. It also defines the evaluation methods, approval rules, packaging, transportation as well as storage. The producer can trial produce it according to individual demands for tungsten powder for unique objectives and armed forces use.

Use tungsten powder
Tungsten powder is the primary basic material for processing powder metallurgy items as well as tungsten alloys. Pure tungsten powder can be made right into cable, rod, tube, plate as well as various other processing materials as well as products of a specific form. Tungsten powder blended with various other steel powders can be made right into various tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy as well as high-density tungsten alloy. Another essential application of tungsten powder is to make tungsten carbide powder, which can be utilized to make cemented carbide tools, such as turning tools, milling cutters, drills as well as moulds.

Price of tungsten powder
Tungsten powder particle dimension and also purity will certainly impact the product'' s price, and also the purchase quantity can also impact the expense of tungsten powder. A huge quantity of huge quantity will be lower. The cost of tungsten powder can be found on our business'' s main site.
