200 mesh tungsten powder is a type of tungsten that’s been made specifically to printing 3D. This dust is meticulously created to help make the form of a curved that’s why each dust compound being extremely homogeneous and small in amounts, allowing for outstanding printing results.

What’s tungsten dust?

Tungsten dust is a credit card applicatoin of powdered metallic tungsten, applied as a fresh solution for the preparing of tungsten-processed substances such as for instance for example alloys, tungsten items and. It is a gray-black material with a metallic Lustre (body-centred cubic crystal). Melting period 3400. Boiling facets 5555. The tungsten’s hardness is probably the most difficult of the metals. The hardest tungsten pole is 200250 and it’s the hardest tungsten pole that’s been spun after the twisting claw spins is 350400. It’s soluble within the combine p of nitric p as well as hydrofluoric acid. It touches in the mix of salt hydroxide and carbonate. A little soluble in nitric p and sulfuric p as well as aqua regia, insoluble in hydrofluoric p and water. potassium hydroxide. Tungsten has two forms A and B. At standard temperature and atmospheric pressure, type A is a solid circular style that is body-centered. Sort B tungsten is ready are available in the current presence of oxygen. It’s protected to 630degC, and then turns to a tungsten at problems around 630degC. This approach is unreversible.

Huge difference between tungsten dust and curved tungsten dust

Tungsten dust and tungsten curved dust are both dust kinds of tungsten, but they’ve clear variations in morphology, compound measurement and application.


Tungsten dust is usually in granular variety, while curved tungsten dust is a curved dust subsequent unique processing. This curved form allows tungsten dust to motion and load higher in programs such as for instance for example 3D printing, providing more standard printing results.

Chemical Size

While tungsten cereals have somewhat huge compound forms, curved tungsten cereals have very great compound forms, usually in the nanometer range. This great compound measurement allows Circular Tungsten Powder to match higher into the nozzle of the 3D printer, providing higher printing details. At the same time, the great particles may also be capable to load the printing rest, increasing the density and energy of the printed part.


Tungsten dust carries a wide selection of programs in several fields, such as for instance for example lamp production, engineering, and physical parts. In these programs, tungsten dust is generally used as a product or alloying element. Circular tungsten dust, on another give, is quite perfect for places such as for instance for example 3D printing, wherever it’s prepared of fabricating more difficult, high-precision parts and items since outstanding flowability, stuffing influence and printability.

How do you want to make tungsten dust?

It’s produced by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The task of creating the tungsten dust through hydrogen decrease could be split into two phases one time in the first position, at problems of 500-700degC, tungsten oxide is decreased to tungsten oxide; in the next period, at 700-900°C which period tungsten dioxide will undoubtedly be decreased to the tungsten powder. The decrease effect is normally done by the appropriate execution of a pipe or rotary furnace.

The potency of tungsten decreased dust (such as quality as well as compound measurement, layout, measurement, etc.) largely depends in the means of reduction. In the behave of lowering tungsten in a oven pipe, the principal facets that impact the rate of decrease are problems of decrease, amount of tungsten oxide into the burner vessel and the pace of activity that the vessel is in, as well as the rate of motion of hydrogen, and the total amount of water in hydrogen. Since the problems of decrease, measurement of tungsten dust gets more coarse.

Production of tungsten dust coupled with method of hydrogen decrease, there’s also a tungsten oxide carbon decrease practices applied originally The decrease temperature is significantly more than 1050 degrees Celsius.The enjoy of the tungsten oxide dust that is created that way is poor. Furthermore, with the utilization of calcium, metal zinc, and some other decrease features of tungsten oxide research is underway. For particular programs that want ultra-fine, ultrapure compound measurement of tungsten dust the development of the tungsten chloride hydrogen decrease method The tungsten dust compound measurement is less than 0.05mm.

Industrial production may be achieved through the reduction of tungsten trioxide by hydrogen, or ammonium partungstate is treated with p and then tungsten trioxide could be produced by maturation decomposition and then decreased using hydrogen.

Hydrogen decrease using tungsten trioxide hydrogen decrease could be achieved in two actions The 1st position is when tungsten trioxide heating to 550-800 , using hydrogen reduction. Another position of decrease occurs between 650 and 850 the tungsten dust is finished.

Also, it’s possible to cut back ammonium paratungstate in to blue tungsten oxide (blue tungsten) actually by hydrogen, or, or even by hydrogen then reduce it back again to tungsten by hydrogen. The measurement and product of the tungsten dust are a substantial quality signal of the tungsten powder. The decrease method is done via a pipe or the rotary furnace.

Circular tungsten dust has the following benefits:

Circular form: The curved form allows the tungsten dust to raised load the printing rest through the printing method, providing a far more standard printing result. Considered against normal granular tungsten dust, curved tungsten dust may higher conform to the 3D printing mind and offer an easier printing process.

Great compound measurement: The great compound measurement allows the tungsten dust to raised match into the nozzle of the 3D printer, providing higher printing details. The great particles also load the printing rest higher, increasing the density and energy of the printed part.

Standard compound flow: Standard compound flow reduces clogging and flaws through the printing method and increases printing success. In normal granular tungsten cereals, the compound flow is usually maybe not standard enough, which can result in clogging or flaws through the printing process. The standard compound flow of curved tungsten dust may effortlessly handle this problem.

Large enjoy: High-purity tungsten dust can provide higher printing efficiency and greater printing quality. In a couple of programs, it must use high-purity solution for printing to ensure the quality and efficiency of parts.

Circular Tungsten Powder Plan Areas

Circular tungsten dust carries a wide selection of programs, including while not restricted to the following places:

Aerospace: Circular tungsten dust can be utilized to produce high-performance parts such as for instance for example aircraft structural parts and engine parts. In these programs, the large energy, large density and large enjoy top features of tungsten dust can provide higher printing efficiency and quality.

Automotive industry: Circular tungsten is useful for the production of parts for automobiles, including body parts, engine parts and different parts. The solid toughness and opposition to temperature of tungsten dust may increase printing quality and performance.

Medical matter Circular tungsten can be utilized to make medical items like dental implants, medical units and others. The large biocompatibility as well as the large energy of tungsten dust could increase printing quality and printing performance.

Architecture: Circular tungsten dust can be utilized to produce architectural designs and components. The large energy and wear-resistant properties of tungsten dust can provide higher printing efficiency and quality.

Technology: Circular tungsten dust can be utilized to produce electronics, such as for instance for example semiconductor items, signal cells and so on. The large thermal and electric conductivity of tungsten dust can provide higher printing efficiency and quality.

It must be observed that using curved tungsten dust for 3D printing takes a specific amount of skill and experience. If you’re a newcomer, it’s chosen to use with even more available 3D printing materials first. At the same time, using tungsten dust for 3D printing also requires unique focus on safety, as tungsten is a high-density material which could only trigger damage to the patient body. When this, be sure to follow the applicable safety rules and running procedures.
