  • Recycling of tungsten carbide scrap metal: A review of

    1 Introduction Among the many applications tungsten is known for, its most important use today is in the production of tungsten carbide, also referred to as cemented carbide or hardmetal (Sandvik, 2016, Exner, 1979)The main constituent in this composite material is tungsten monocarbide (WC), which has hardness close to that of diamond ()Other transition metal carbides such as TiC,Spherical cast tungsten carbide powder Phildal tungsten co, limited is becoming a significant tungsten material supplier and exporter Character: the microstructure of spherical cast tungsten carbide is homogeneous, dense and featherlike structure, and spherical cast tungsten carbide has stable chemical properties, good processing performance high hardness, good Applications: widely used forCrystal Tungsten Carbide Powder by Daao Industry Co, Ltd
