What is tungsten powder?
Tungsten powder is lowered with hydrogen in a four-tube muffle furnace or a multi-tube heater making use of tungsten oxide as the raw product. The fragment dimension varies from 0.6-30 microns. It is generally separated right into crude, medium and also fine bits, silver grey powder. The pollutant web content is based on the nationwide standard. It is prepared by hydrogen decrease of tungsten trioxide or ammonium para tungstate. The procedure of preparing tungsten powder by hydrogen reduction is typically separated into two phases: the initial stage is the decrease of tungsten trioxide to tungsten dioxide at 500 ~ 700oC; In the 2nd phase, tungsten dioxide is minimized to tungsten powder at 700 ~ 900oC. The decrease response is usually accomplished in a tubular electric furnace or a rotary heating system. The performance of the minimized tungsten powder (such as purity, bit dimension, bit dimension structure, and so on) primarily depends on the reduction process. When tungsten powder is decreased in a tubular furnace, the primary process parameters that impact the reduction price are the reduction temperature, the amount of tungsten oxide in the burning boat, the burning boat moving rate, the flow rate of hydrogen and also the dampness web content in hydrogen. With the boost of the reduction temperature level, the bit size of tungsten powder comes to be crude.

Qualities as well as criteria of tungsten powder
Along with particular demands for the contamination web content of tungsten powder, the oxygen web content need to be regulated within a specific range. The particle dimension of commonly made use of tungsten powder is typically 2 ~ 10 of the typical Fisher dimension μ & mu; m. Tungsten powder is in the shape of polygonal fragments. Furthermore, the specific surface area, bulk density and also faucet thickness of tungsten powder also vary within a certain array. The residential properties of tungsten powder straight influence the manufacturing of tungsten materials and the high quality of tungsten powder metallurgy items, particularly in pureness and bit dimension. Tungsten powder is identified according to pureness, fragment size, as well as different uses The earliest manufacturing of tungsten powder is to divide hydrogen-reduced tungsten powder into 3 qualities according to chemical purity; Japan has developed the industrial criterion of Tungsten Powder and Tungsten Carbide Powder (JISH2116-1979); Britain, France, the previous Soviet Union and other countries all have actually linked nationwide standards for tungsten powder. In 1982, the Technical Conditions for Hydrogen Reduction of Tungsten Powder (GB3458-82) was created for tungsten powder created in China. This common defines the properties and classification qualities of tungsten powder. It also defines the evaluation techniques, approval policies, packaging, transportation and storage. The supplier can test create it according to customer demands for tungsten powder for special purposes as well as armed forces usage.

Use of tungsten powder
Tungsten powder is the primary resources for processing powder metallurgy items and tungsten alloys. Pure tungsten powder can be made right into wire, pole, tube, plate and also various other handling products and also items of a certain form. Tungsten powder combined with other metal powders can be made into numerous 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 concrete carbide tools, such as turning devices, grating cutters, drills and also moulds.

Rate of tungsten powder
Tungsten powder bit dimension and also pureness will influence the item'' s cost, and also the purchase volume can likewise influence the price of tungsten powder. A big amount of large amount will certainly be reduced. The price of tungsten powder can be found on our company'' s official website.
