What is Circular Tungsten Powder?

3d printing tungsten is a kind of tungsten that has been created specifically to printing 3D. This dust is meticulously made to form the design of a round that is why each dust particle being excessively homogeneous and small in size, permitting outstanding making results.

What’s tungsten dust?

Tungsten dust is a questionnaire of powdered metallic tungsten, utilized as a raw substance for the preparation of tungsten-processed substances such as for example alloys, tungsten products and services and. It is just a gray-black steel with a metallic Lustre (body-centred cubic crystal). Reduction stage 3400. Boiling details 5555. The tungsten’s hardness is the absolute most hard of the metals. The toughest tungsten rod is 200250 and it’s the toughest tungsten rod that has been spun after the rotating hammer revolves is 350400. It’s soluble within the combine p of nitric p along with hydrofluoric acid. It touches in the combination of salt hydroxide and carbonate. A little soluble in nitric p and sulfuric p along with aqua regia, insoluble in hydrofluoric p and water. potassium hydroxide. Tungsten has two varieties A and B. At regular heat and atmospheric force, form A is just a solid cylindrical framework that is body-centered. Type T tungsten is able can be found in the presence of oxygen. It’s secure to 630degC, and then turns to a tungsten at conditions above 630degC. This process is unreversible.

Huge difference between tungsten dust and round tungsten dust

Tungsten dust and tungsten round dust are generally dust types of tungsten, but they’ve obvious differences in morphology, particle measurement and application.


Tungsten dust is generally in granular form, while round tungsten dust is just a round dust after unique processing. This round form enables tungsten dust to flow and fill better in applications such as for example 3D making, providing more uniform making results.

Chemical Size

While tungsten grains have relatively large particle shapes, round tungsten grains have really great particle shapes, frequently in the nanometer range. This great particle measurement enables Round Tungsten Powder to fit better into the nozzle of the 3D printer, providing finer printing details. At the same time frame, the great particles may also be in a position to fill the printing bed, increasing the density and power of the produced part.


Tungsten dust features a wide variety of applications in several areas, such as for example lamp manufacturing, electronics, and technical parts. In these applications, tungsten dust is frequently used as a product or alloying element. Round tungsten dust, on another hand, is particularly suitable for areas such as for example 3D making, where it’s able of creating more technical, high-precision elements and units because of its outstanding flowability, stuffing influence and printability.

How will you prepare tungsten dust?

It’s made by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The procedure of earning the tungsten dust through hydrogen decrease could be divided into two periods one period in the initial period, at conditions of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the 2nd period, at 700-900°C where stage tungsten dioxide will undoubtedly be reduced to the tungsten powder. The decrease response is usually executed by the form of a tube or circular furnace.

The performance of tungsten reduced dust (such as quality along with particle measurement, structure, measurement, etc.) largely depends in the method of reduction. In the act of reducing tungsten within an range tube, the principal factors that affect the rate of decrease are conditions of decrease, number of tungsten oxide into the burner vessel and the pace of action that the vessel is in, along with the rate of flow of hydrogen, and the quantity of humidity in hydrogen. As the conditions of decrease, measurement of tungsten dust gets more coarse.

Generation of tungsten dust along with the way of hydrogen decrease, there is also a tungsten oxide carbon decrease methods used initially The decrease heat is higher than 1050 degrees Celsius.The love of the tungsten oxide dust that is produced like this is poor. Additionally, with the usage of calcium, metal zinc, and various other decrease processes of tungsten oxide study is currently underway. For particular applications that need ultra-fine, ultrapure particle measurement of tungsten dust the growth of the tungsten chloride hydrogen decrease process The tungsten dust particle measurement is less than 0.05mm.

Commercial manufacturing may be performed through the reduced total of tungsten trioxide by hydrogen, or ammonium partungstate is handled with p and then tungsten trioxide could be made by maturation decomposition and then reduced applying hydrogen.

Hydrogen decrease applying tungsten trioxide hydrogen decrease could be achieved in two measures The first period is when tungsten trioxide heating to 550-800 , applying hydrogen reduction. The next period of decrease occurs between 650 and 850 the tungsten dust is finished.

Also, it’s probable to reduce ammonium paratungstate into orange tungsten oxide (blue tungsten) originally by hydrogen, or, or even by hydrogen then minimize it back once again to tungsten by hydrogen. The measurement and content of the tungsten dust are an essential quality indicator of the tungsten powder. The decrease process is performed via a tube or the circular furnace.

Round tungsten dust has the next benefits:

Round form: The round form enables the tungsten dust to raised fill the printing bed during the making process, providing an even more uniform printing result. Compared with standard granular tungsten dust, round tungsten dust may better conform to the 3D making mind and provide a softer making process.

Fine particle measurement: The great particle measurement enables the tungsten dust to raised fit into the nozzle of the 3D printer, providing finer printing details. The great particles also fill the printing bed better, increasing the density and power of the produced part.

Standard particle distribution: Standard particle distribution reduces clogging and flaws during the making process and increases printing success. In standard granular tungsten grains, the particle distribution is generally not uniform enough, that may cause clogging or flaws during the making process. The uniform particle distribution of round tungsten dust may efficiently solve that problem.

Large love: High-purity tungsten dust can provide better printing performance and higher printing quality. In a few applications, it’s essential to utilize high-purity substance for making to guarantee the quality and performance of parts.

Round Tungsten Powder Software Places

Round tungsten dust features a wide variety of applications, including however not limited by the next areas:

Aerospace: Round tungsten dust can be utilized to manufacture high-performance elements such as for example airplane architectural parts and engine parts. In these applications, the large power, large density and large love faculties of tungsten dust can provide better making performance and quality.

Automotive business: Round tungsten is used for the manufacturing of elements for automobiles, including chassis elements, engine parts and other parts. The powerful longevity and resistance to heat of tungsten dust can enhance making quality and performance.

Medical subject Round tungsten can be utilized to produce medical units like dental implants, operative devices and others. The large biocompatibility along with the large power of tungsten dust can enhance printing quality and making performance.

Architecture: Round tungsten dust can be utilized to manufacture architectural versions and components. The large power and wear-resistant qualities of tungsten dust can provide better making performance and quality.

Electronics: Round tungsten dust can be utilized to manufacture electronics, such as for example semiconductor units, signal boards and therefore on. The large thermal and electric conductivity of tungsten dust can provide better making performance and quality.

It should be noted that applying round tungsten dust for 3D making takes a particular degree of ability and experience. If you should be a novice, it is preferred to rehearse with more available 3D making products first. At the same time frame, applying tungsten dust for 3D making also requires unique attention to protection, as tungsten is just a high-density steel that could easily trigger injury to the human body. When this, make sure to follow the relevant protection regulations and operating procedures.
