How about the tungsten alloy made of tungsten powder
What is tungsten powder?
Tungsten powder is lowered with hydrogen in a four-tube muffle heater or a multi-tube furnace utilizing tungsten oxide as the raw material. The particle size varies from 0.6-30 microns. It is generally separated right into rugged, medium and also great fragments, silver grey powder. The impurity material is based on the national 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 split into 2 phases: the first stage is the reduction of tungsten trioxide to tungsten dioxide at 500 ~ 700oC; In the 2nd phase, tungsten dioxide is lowered to tungsten powder at 700 ~ 900oC. The decrease reaction is normally performed in a tubular electrical furnace or a rotary heating system. The efficiency of the reduced tungsten powder (such as pureness, fragment dimension, bit size make-up, and so on) primarily relies on the reduction process. When tungsten powder is reduced in a tubular furnace, the major process specifications that affect the reduction price are the reduction temperature level, the quantity of tungsten oxide in the burning boat, the burning boat moving rate, the flow rate of hydrogen and the moisture content in hydrogen. With the boost of the reduction temperature level, the fragment dimension of tungsten powder ends up being crude.
Residences as well as requirements of tungsten powder
Along with particular demands for the pollutant web content of tungsten powder, the oxygen web content should be managed within a specific range. The bit size of generally made use of tungsten powder is generally 2 ~ 10 of the average Fisher size μ & mu; m. Tungsten powder remains in the form of polygonal bits. Furthermore, the specific surface, mass thickness as well as tap thickness of tungsten powder likewise vary within a specific variety. The residential or commercial properties of tungsten powder straight impact the manufacturing of tungsten materials and also the high quality of tungsten powder metallurgy products, especially in purity and particle size. Tungsten powder is classified according to pureness, fragment size, and also various uses The earliest manufacturing of tungsten powder is to separate hydrogen-reduced tungsten powder right into 3 grades according to chemical pureness; Japan has actually created the industrial requirement of Tungsten Powder and also Tungsten Carbide Powder (JISH2116-1979); Britain, France, the former Soviet Union and also various other nations all have actually unified nationwide 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 homes and also category grades of tungsten powder. It additionally defines the assessment approaches, acceptance rules, product packaging, transportation and also storage space. The manufacturer can trial produce it according to individual needs for tungsten powder for unique objectives as well as military use.
Use of tungsten powder
Tungsten powder is the major resources for handling powder metallurgy products and tungsten alloys. Pure tungsten powder can be made into cord, rod, tube, plate as well as various other handling materials as well as items of a certain 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. An additional essential application of tungsten powder is to make tungsten carbide powder, which can be used to make cemented carbide tools, such as turning tools, milling cutters, drills as well as moulds.
Cost of tungsten powder
Tungsten powder fragment dimension and purity will certainly impact the item'' s price, as well as the acquisition quantity can additionally impact the cost of tungsten powder. A large quantity of big amount will be reduced. The rate of tungsten powder can be found on our company'' s official website.
