What are the Properties and Uses of Spherical Tungsten Carbide

The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.

Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the Tungsten Carbide may also be affected to a certain extent.

What is Tungsten Carbide?

As one of the main production raw materials of cemented carbide, the physical and chemical properties of tungsten carbide (WC) powder, such as particle shape, particle size, particle size distribution, oxygen content, carbon content, bulk density, etc., will directly affect the quality of alloy products. Nowadays, with the gradual optimization of the production process of cemented carbide, the market demand for spherical tungsten carbide powder is also increasing.


Tungsten carbide is mainly composed of refractory metal tungsten and non-metallic carbon, and contains a small amount of impurity elements such as Co, Cr, Ti, Ta, Nb, V, Mn, Ni, Mo, O, etc. According to the different particle size, it can be divided into the following grades, WC10 (1.01~1.40um), WC30 (3.01~4.00um), WC50 (5.01~7.00um), WC100 (10.01~14.00um) and so on.


Properties of spherical tungsten carbide

Appearance is black powder, high purity ≥99.9%, sphericity ≥95%, melting point is 2870℃, boiling point is 6000℃, density is 15.63g/cm³, bulk density is greater than 7.0g/cm3, tap density is greater than 7.0. 5g/cm3, the flow performance is less than 10.0s/50g, and has the characteristics of high hardness, low thermal expansion coefficient, high compressive strength, large elastic modulus, and smooth surface. However, due to its high hardness, its processing performance is poor, so it is more suitable for 3D printing.


Production process of spherical tungsten carbide powder

Smelting method: The raw material powder (tungsten powder and carbon black or tungsten powder, carbon black and tungsten carbide) is melted into a liquid state, and droplets will form on the surface under the action of centrifugal rotation method, rotary atomization method or gas atomization method Spherical tungsten carbide.


Modified irregular tungsten carbide: The irregular WC is melted into a liquid state, and then the spherical tungsten carbide powder is made by the plasma spheroidization method or the resistance heat spheroidization method.


Uses of spherical tungsten carbide

Mainly used in the production of cemented carbide. According to different chemical compositions, cemented carbides can be divided into tungsten-cobalt, tungsten-titanium-cobalt and tungsten-titanium-tantalum (niobium) types.
