Tungsten carbide powder is produced by the carburization of tungsten carbide powder and a range of powder qualities in regard to average particle size (0.15–12µm) is produced. The conventional process of carburisation in the global tungsten carbide powder market comprises mixing of the tungsten carbide powder of desired particle size with high purity carbon (lamp black or graphite) and reacting at temperatures between 1,300 to 1,600°C in hydrogen atmosphere. The average particle size and particle size distribution of the original tungsten carbide powder determine size and distribution of the WC powder.
The final carbon content of the WC Powder depends on the production mode of the hard metal producer and varies from slightly sub-stoichiometric to stoichiometric (6.13% C) to slightly over-stoichiometric. The tungsten carbide powder also depends on the average particle size, particle size distribution, apparent (bulk) density and homogeneity.
High temperature carburised WC powders (1,700–2,200 °C) are usually coarse 10 to 50µm though the percentage production is less. Tungsten carbide powder is packaged in sealed polyethylene-lined steel drums.
It comprises of equal parts of carbon and tungsten atoms. They are available as a fine gray powder. Tungsten carbide powder can be pressed to form different shapes for use in abrasives, cutting tools, armor-piercing rounds, industrial machinery, instruments, jewelry and other tools. It is about two times stiffer than steel. It is known to be much denser than steel or titanium. They have a stiffness of about 550 GPa as per measured using Young’s modulus. The hardness of the product can be compared with ruby, sapphire or corundum. It can be polished or finished using abrasives that have superior hardness.
Tungsten carbide powder find applications in machine tools and components, cutting tools, dies and punches, abrasive products and others. They also find applications in varied end use industry such as mining and construction, industrial engineering, transportation, oil and gas, aerospace and defence and others. Tungsten carbide cutting surfaces are used in the machineries through material such as stainless steel and carbon steel. Tungsten carbide is used in tools that are at higher risk of getting worn off. They are widely used in high quantity production runs. Tungsten carbide powder, when used in manufacturing several cutting tools offer better finish on parts and also provides high temperature resistance which in turn helps in achieving faster machining. Owing to the superior properties of finished products many manufacturers are using the powder to manufacture a wide range of cutting tools. Tungsten carbide powder is also used to manufacture ammunition.
