Dark grey Tungsten Carbide Powder with 99.8% WC content for making cemented carbide

Dark grey Tungsten Carbide Powder with 99.8% WC content for making cemented carbide
 

Description:
 
Our tungsten carbide powder is manufactured by the conventional method - carburization of tungsten powder. Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical formula is WC, its hardness is close to diamond. 
 
Tungsten carbide is approximately three times stiffer than steel, with a Young's modulus of approximately 550 GPa, and is much denser than steel or titanium. Tungsten carbide is insoluble in water, hydrochloric acid or sulfuric acid, while it can dissolves in nitric & hydrofluoric mixed acid. Pure tungsten carbide phase is original brittle, but if blended with certain amount of titanium, cobalt or other metals, toughness will relatively increase.
 
The final carbon content of the WC Powder depends on the production mode of the hardmetal producer and is one item of the rigid specification, and varies from slightly substoichiometric to stoichiometric (6.13% C) to slightly over-stoichiometric.  But not only is the carbon content specified but also a series of physical properties including: average particle size, particle size distribution, apparent (bulk) density and homogeneity.
