What is Round Tungsten Powder?

200 mesh tungsten powder is a kind of tungsten that’s been created specifically to print 3D. That dust is meticulously produced to create the design of a spherical that is why each dust particle being exceptionally homogeneous and small in size, permitting exemplary making results.

What’s tungsten dust?

Tungsten dust is a questionnaire of powdered metallic tungsten, used as a natural substance for the planning of tungsten-processed ingredients such as for instance alloys, tungsten services and products and. It is just a gray-black metal with a metallic Lustre (body-centred cubic crystal). Melting position 3400. Boiling items 5555. The tungsten’s hardness is probably the most difficult of the metals. The toughest tungsten rod is 200250 and it is the toughest tungsten rod that’s been spun after the spinning claw revolves is 350400. It is soluble within the combine acid of nitric acid along with hydrofluoric acid. It melts in the mix of sodium hydroxide and carbonate. A little soluble in nitric acid and sulfuric acid along with aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two versions A and B. At typical heat and atmospheric force, form A is just a stable round structure that is body-centered. Form W tungsten is ready can be found in the clear presence of oxygen. It is stable to 630degC, and then changes to a tungsten at conditions over 630degC. That process is unreversible.

Huge difference between tungsten dust and spherical tungsten dust

Tungsten dust and tungsten spherical dust are both dust kinds of tungsten, but they’ve obvious differences in morphology, particle measurement and application.


Tungsten dust is usually in granular sort, while spherical tungsten dust is just a spherical dust after special processing. That spherical shape enables tungsten dust to movement and fill greater in applications such as for instance 3D making, providing more uniform making results.

Particle Measurement

While tungsten powders have relatively large particle measurements, spherical tungsten powders have very great particle measurements, frequently in the nanometer range. That great particle measurement enables Round Tungsten Dust to fit greater into the nozzle of the 3D printer, providing better print details. At the same time frame, the great particles are also able to fill the print sleep, increasing the thickness and strength of the printed part.


Tungsten dust features a wide range of applications in many fields, such as for instance lamp production, technology, and technical parts. In these applications, tungsten dust is usually used as a filler or alloying element. Round tungsten dust, on one other hand, is specially ideal for areas such as for instance 3D making, wherever it is ready of fabricating more complex, high-precision pieces and products because of its exemplary flowability, stuffing effect and printability.

How will you prepare tungsten dust?

It is made by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The method of earning the tungsten dust through hydrogen decrease may be divided into two phases one period in the initial period, at conditions of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the second period, at 700-900°D at which position tungsten dioxide will be reduced to the tungsten powder. The decrease response is usually performed by the shape of a tube or circular furnace.

The effectiveness of tungsten reduced dust (such as quality along with particle measurement, arrangement, measurement, etc.) largely depends in the strategy of reduction. In the act of lowering tungsten in a oven pipe, the principal factors that affect the rate of decrease are conditions of decrease, amount of tungsten oxide into the burner vessel and the speed of movement that the vessel is in, along with the rate of movement of hydrogen, and the amount of water in hydrogen. As the conditions of decrease, measurement of tungsten dust gets more coarse.

Manufacturing of tungsten dust combined with approach to hydrogen decrease, there’s also a tungsten oxide carbon decrease practices employed in the beginning The decrease heat is more than 1050 levels Celsius.The love of the tungsten oxide dust that is made that way is poor. More over, with the utilization of calcium, metal zinc, and several other decrease procedures of tungsten oxide research happens to be underway. For certain applications that want ultra-fine, ultrapure particle measurement of tungsten dust the development of the tungsten chloride hydrogen decrease process The tungsten dust particle measurement is less than 0.05mm.

Professional manufacturing may be achieved through the reduced total of tungsten trioxide by hydrogen, or ammonium partungstate is handled with acid and then tungsten trioxide may be made by maturation decomposition and then reduced applying hydrogen.

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

Also, it is possible to cut back ammonium paratungstate in to blue tungsten oxide (blue tungsten) initially by hydrogen, or, or even by hydrogen then reduce it back again to tungsten by hydrogen. The measurement and material of the tungsten dust are an essential quality indicator of the tungsten powder. The decrease process is completed through a pipe or the circular furnace.

Round tungsten dust has the following benefits:

Round shape: The spherical shape enables the tungsten dust to better fill the print sleep during the making process, providing a more uniform print result. Weighed against traditional granular tungsten dust, spherical tungsten dust may greater conform to the 3D making head and give a softer making process.

Fine particle measurement: The great particle measurement enables the tungsten dust to better fit into the nozzle of the 3D printer, providing better print details. The great particles also fill the print sleep greater, increasing the thickness and strength of the printed part.

Uniform particle distribution: Uniform particle distribution decreases clogging and problems during the making process and increases print success. In traditional granular tungsten powders, the particle distribution is usually not uniform enough, which can result in clogging or problems during the making process. The uniform particle distribution of spherical tungsten dust may successfully resolve that problem.

Large love: High-purity tungsten dust can offer greater print performance and higher print quality. In certain applications, it is necessary to use high-purity substance for making to ensure the quality and performance of parts.

Round Tungsten Dust Application Parts

Round tungsten dust features a wide range of applications, including however not restricted to the following areas:

Aerospace: Round tungsten dust may be used to production high-performance pieces such as for instance airplane architectural parts and motor parts. In these applications, the large strength, large thickness and large love characteristics of tungsten dust can offer greater making performance and quality.

Automotive industry: Round tungsten is used for the manufacturing of pieces for automobiles, including chassis pieces, motor parts and other parts. The solid durability and resistance to heat of tungsten dust will increase making quality and performance.

Medical subject Round tungsten may be used to create medical products like dental implants, medical tools and others. The large biocompatibility along with the large strength of tungsten dust could increase print quality and making performance.

Architecture: Round tungsten dust may be used to production architectural types and components. The large strength and wear-resistant houses of tungsten dust can offer greater making performance and quality.

Technology: Round tungsten dust may be used to production gadgets, such as for instance semiconductor products, world boards and so on. The large thermal and electric conductivity of tungsten dust can offer greater making performance and quality.

It should be noted that applying spherical tungsten dust for 3D making requires a particular amount of skill and experience. If you should be a novice, it is preferred to apply with some more available 3D making materials first. At the same time frame, applying tungsten dust for 3D making also involves special attention to protection, as tungsten is just a high-density metal that will easily trigger harm to the individual body. When this, be sure to follow the applicable protection rules and operating procedures.
