What are the Properties and Uses of Spherical Tungsten Carbide
The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on Tungsten Carbide.
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.

The Tungsten Carbide industry has experienced demand expectations driven by the rise and the off-season tired stock driven by the seasonal decline in two rounds of the market. Affected by the COVID-19 epidemic and other factors, inventories of manufacturers continue to accumulate, putting pressure on market sentiment. In addition to off-season factors, the weak trend of Tungsten Carbide also reflects the market's concern about the epidemic and some other related enterprises' financial situation.
