WC powder was obtained from recycling cemented carbide scraps. This metal power contained tungsten carbide (WC) at 89.17% titanium (Ti) at 4.90% tantalum (Ta) at 3.56% niobium (Nb) at 1.31% and molybdenum (Mo) at 0.93%. Its particle size and distribution was in the range of 0.03-85.31 µm. After quality improvement of the metal powder by ball milling screening and separating the compounds the result showed that the particle size of the metal powder was decreased to 0.01-0.10 µm (10-100 nm). The average size of the powdered particle was 28 nm. The tungsten powder was in more perfect condition by 95.85%
