What are the Properties and Uses of Spherical Tungsten Carbide
Oil futures tumbled more than $5 a barrel on news that the Biden administration is considering releasing about 1 million barrels a day from the U.S. Strategic Petroleum Reserve (SPR) for several months to cool surging crude prices.
Brent crude futures were down $4.71, or 4.2 percent, at $108.58 a barrel by 0035 GMT. U.S. West Texas Intermediate futures fell $5.45, or 5 percent, to $102.74 a barrel.
At an earlier time, gasoline prices had already reached record levels because of the Russia-Ukraine conflict.
The prices of other commodities like the Tungsten Carbide are also expected to be volatile.
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.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Tungsten Carbide, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the Tungsten Carbide chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.
The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment. For more information about Tungsten Carbide, please feel free to contact us.
