What is tungsten powder?
Tungsten powder is reduced with hydrogen in a four-tube muffle furnace or a multi-tube heating system using tungsten oxide as the raw product. The bit size ranges from 0.6-30 microns. It is primarily divided into coarse, tool and also great particles, silver grey powder. The pollutant web content is based upon the nationwide requirement. It is prepared by hydrogen reduction of tungsten trioxide or ammonium para tungstate. The procedure of preparing tungsten powder by hydrogen reduction is usually divided right into 2 stages: the initial 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 decrease reaction is usually performed in a tubular electric furnace or a rotary heating system. The performance of the minimized tungsten powder (such as pureness, fragment size, fragment size make-up, etc) mostly depends upon the reduction procedure. When tungsten powder is lowered in a tubular furnace, the main procedure specifications that affect the reduction rate are the reduction temperature, the amount of tungsten oxide in the burning boat, the burning watercraft moving speed, the circulation rate of hydrogen and also the dampness material in hydrogen. With the increase of the decrease temperature, the particle dimension of tungsten powder comes to be crude.

Properties and also criteria of tungsten powder
Along with particular needs for the contamination content of tungsten powder, the oxygen content must be controlled within a specific variety. The fragment dimension of generally used tungsten powder is typically 2 ~ 10 of the average Fisher dimension μ & mu; m. Tungsten powder remains in the shape of polygonal particles. Additionally, the certain area, mass density and faucet density of tungsten powder likewise differ within a specific array. The homes of tungsten powder directly influence the production of tungsten products as well as the quality of tungsten powder metallurgy items, specifically in purity and particle size. Tungsten powder is identified according to purity, bit dimension, and different usages The earliest production of tungsten powder is to split hydrogen-reduced tungsten powder right into three qualities according to chemical pureness; Japan has actually formulated the industrial standard of Tungsten Powder and also Tungsten Carbide Powder (JISH2116-1979); Britain, France, the former Soviet Union and various other nations all have merged nationwide criteria for tungsten powder. In 1982, the Technical Problems for Hydrogen Decrease of Tungsten Powder (GB3458-82) was developed for tungsten powder produced in China. This typical defines the buildings and category grades of tungsten powder. It likewise defines the examination approaches, approval policies, product packaging, transportation and also storage. The supplier can test create it according to customer requirements for tungsten powder for special purposes as well as armed forces use.

Use tungsten powder
Tungsten powder is the main resources for handling powder metallurgy items as well as tungsten alloys. Pure tungsten powder can be made right into cord, rod, tube, plate and various other handling products and items of a particular shape. Tungsten powder blended with other metal powders can be made into numerous tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy and high-density tungsten alloy. Another crucial application of tungsten powder is to make tungsten carbide powder, which can be used to make cemented carbide devices, such as turning devices, crushing cutters, drills and also moulds.

Cost of tungsten powder
Tungsten powder fragment size as well as pureness will certainly affect the item'' s rate, and the purchase volume can also impact the expense of tungsten powder. A big amount of huge quantity will be lower. The cost of tungsten powder can be discovered on our firm'' s main internet site.
