Round Sphericaltungsten powder is a kind of tungsten that has been created specifically to printing 3D. This powder is meticulously produced to make the form of a spherical that is why each powder particle being acutely homogeneous and small in proportions, allowing for outstanding making results.

What is tungsten powder?

Tungsten powder is an application of powdered metallic tungsten, employed as a raw product for the preparation of tungsten-processed ingredients such as alloys, tungsten services and products and. It is really a gray-black steel with a metallic Lustre (body-centred cubic crystal). Melting level 3400. Boiling factors 5555. The tungsten’s hardness is the most hard of the metals. The toughest tungsten rod is 200250 and it’s the toughest tungsten rod that has been spun following the rotating claw revolves is 350400. It’s soluble within the combine acid of nitric acid in addition to hydrofluoric acid. It melts in the mix of sodium hydroxide and carbonate. Only a little soluble in nitric acid and sulfuric acid in addition to aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two varieties A and B. At usual heat and atmospheric pressure, type A is really a strong cylindrical framework that is body-centered. Form T tungsten is ready found in the clear presence of oxygen. It’s stable to 630degC, and then transforms to a tungsten at temperatures above 630degC. This process is unreversible.

Big difference between tungsten powder and spherical tungsten powder

Tungsten powder and tungsten spherical powder are both powder types of tungsten, but they’ve apparent variations in morphology, particle size and application.


Tungsten powder is generally in granular variety, while spherical tungsten powder is really a spherical powder after particular processing. This spherical form enables tungsten powder to movement and fill greater in purposes such as 3D making, giving more uniform making results.

Chemical Measurement

While tungsten powders have somewhat large particle sizes, spherical tungsten powders have really great particle sizes, generally in the nanometer range. This great particle size enables Round Tungsten Powder to fit greater into the nozzle of the 3D printer, giving finer printing details. At the same time, the great contaminants will also be able to fill the printing bed, increasing the occurrence and power of the printed part.


Tungsten powder has a wide selection of purposes in many fields, such as lamp production, technology, and mechanical parts. In these purposes, tungsten powder is usually applied as a gel or alloying element. Round tungsten powder, on another hand, is very suited to places such as 3D making, wherever it’s ready of fabricating more complex, high-precision components and units because outstanding flowability, filling impact and printability.

How do you prepare tungsten powder?

It’s created by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The process of earning the tungsten powder through hydrogen decrease can be split into two periods one period in the initial period, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the next phase, at 700-900°C at which level tungsten dioxide is likely to be reduced to the tungsten powder. The decrease effect is typically conducted by the proper execution of a tube or circular furnace.

The effectiveness of tungsten reduced powder (such as quality in addition to particle size, arrangement, size, etc.) largely depends in the method of reduction. In the act of reducing tungsten in an range tube, the primary factors that influence the charge of decrease are temperatures of decrease, level of tungsten oxide into the burner vessel and the speed of motion that the vessel is in, in addition to the charge of movement of hydrogen, and the total amount of water in hydrogen. While the temperatures of decrease, size of tungsten powder gets more coarse.

Generation of tungsten powder combined with way of hydrogen decrease, there’s also a tungsten oxide carbon decrease methods used in the beginning The decrease heat is more than 1050 levels Celsius.The love of the tungsten oxide powder that is produced like this is poor. More over, with the use of calcium, metal zinc, and several other decrease procedures of tungsten oxide research is currently underway. For certain purposes that want ultra-fine, ultrapure particle size of tungsten powder the growth of the tungsten chloride hydrogen decrease process The tungsten powder particle size is less than 0.05mm.

Professional generation may be achieved through the reduction of tungsten trioxide by hydrogen, or ammonium partungstate is handled with acid and then tungsten trioxide can be created by maturation decomposition and then reduced using hydrogen.

Hydrogen decrease using tungsten trioxide hydrogen decrease can be achieved in two measures The initial period is when tungsten trioxide heat to 550-800 , using hydrogen reduction. Another period of decrease occurs between 650 and 850 the tungsten powder is finished.

Also, it’s probable to lessen ammonium paratungstate into blue tungsten oxide (blue tungsten) originally by hydrogen, or, if not by hydrogen then lower it back again to tungsten by hydrogen. The size and material of the tungsten powder are an important quality sign of the tungsten powder. The decrease process is completed through a tube or the circular furnace.

Round tungsten powder has the following advantages:

Round form: The spherical form enables the tungsten powder to higher fill the printing bed through the making process, giving a far more uniform printing result. Weighed against conventional granular tungsten powder, spherical tungsten powder may greater adapt to the 3D making head and offer a better making process.

Great particle size: The great particle size enables the tungsten powder to higher match into the nozzle of the 3D printer, giving finer printing details. The great contaminants also fill the printing bed greater, increasing the occurrence and power of the printed part.

Standard particle distribution: Standard particle distribution reduces clogging and problems through the making process and increases printing success. In conventional granular tungsten powders, the particle distribution is generally maybe not uniform enough, which could result in clogging or problems through the making process. The uniform particle distribution of spherical tungsten powder may successfully solve this problem.

High love: High-purity tungsten powder provides greater printing efficiency and larger printing quality. In certain purposes, it’s required to use high-purity product for making to guarantee the quality and efficiency of parts.

Round Tungsten Powder Application Areas

Round tungsten powder has a wide selection of purposes, including but not limited to the following places:

Aerospace: Round tungsten powder can be used to produce high-performance components such as aircraft structural components and motor parts. In these purposes, the high power, high occurrence and high love faculties of tungsten powder provides greater making efficiency and quality.

Automotive market: Round tungsten is useful for the generation of components for automobiles, including framework components, motor components and different parts. The strong longevity and resistance to heat of tungsten powder can enhance making quality and performance.

Medical area Round tungsten can be used to generate medical units like dental implants, surgical devices and others. The high biocompatibility in addition to the high power of tungsten powder could enhance printing quality and making performance.

Structure: Round tungsten powder can be used to produce architectural designs and components. The high power and wear-resistant homes of tungsten powder provides greater making efficiency and quality.

Technology: Round tungsten powder can be used to produce electronics, such as semiconductor units, enterprise boards and therefore on. The high thermal and electric conductivity of tungsten powder provides greater making efficiency and quality.

It should be observed that using spherical tungsten powder for 3D making requires a particular amount of skill and experience. If you should be a beginner, it is preferred to apply with some more accessible 3D making products first. At the same time, using tungsten powder for 3D making also involves particular attention to security, as tungsten is really a high-density steel that may simply trigger harm to the human body. When doing so, make sure you follow the appropriate security rules and operating procedures.
